Fern and Sudane,
Thank you for your input and feedback in this very important matter. I will address both of your questions, concerns, suggestions in one reply. As Sudane points out each SIM was priced as an individual unit as it was brought inworld. Each SIM's tier was calculated based on the amount of billable land (tier paying citizen owned land) to cover the entire cost of that SIM to Linden Labs. The result of this method can be seen by the wide difference in the Tier per SQM rate of our current 5 SIMS.
NFS L$ 1.77
CN L$ 2.26
AM L$ 4.68
LA L$ 3.61
MON L$ 5.73
Sudane I have allowed for the future acquisition of new SIMS in my report. Worksheets NEWSIM1, NEWSIM2, and NEWSIM3 are examples of SIMS modeled after 3 of our current set-ups at my new proposed tier rate. You point out later in your post "Inevitably, however, tier prices WILL rise if we add new SIMS, because all new SIMS will cost us full tier, while right now NFS, CN, and Monastery are all heavily discounted and keep our costs lower as a result."
My response to this is no it will not rise. 3 of the original 5 SIMS are based on earlier pricing by LL. The other two, AM and LA we are already paying current costs to LL. NFS, CN, and MON will retain the tier structure that we approve for them now, regardless if we bring more SIMS inworld because their costs have been grandfathered in.
Sudane I agree with you that we need to establish a target ratio of sold land to unsold land, meaning tier paying citizen owned land and publicly held land. This is especially true if we do make the change to a more unified tier rate for all SIMS. The more publicly held land than the higher the tier cost will be to the tier paying citizens. This is reflected in our varied tier rates that we have now that I presented above. Currently here is a list of all 5 SIMS's privately held land, this is based on the CDS Master Parcel List in my report and does not reflect any inworld situations we are currently under.
NFS 37168sqm 56.71%
CN 41616sqm 63.50%
AM 27648sqm 42.19%
LA 29184sqm 44.53%
MON 6144sqm 9.38%
Even when I was developing my 3 new SIM proposals I was trying to find a happy medium between private/public land. SIM 1 has 45,568sqm of private land. It's a single prim SIM with 2/4096sqm parcels, 4/2048sqm parcels, 15/1024sqm parcels, and 27/512sqm parcels. SIM 2 has 38,912sqm of private land, single prim. 4/2048sqm, 10/1024sqm, 20/512sqm, 40/256sqm. SIM 3 has 27,136sqm of private DOUBLE prim land. 1/4096sqm, 4/2048sqm, 9/1024sqm, 11/512sqm. Private land percentage for these 3 are 69.53%, 59.38%, and 41.41% respectively.
Sudane the other point you mention about a ratio of either tier costs to other costs or a ratio of total revenues to other costs is interesting. I can see using this ratio scenario for budgeting purposes but I don't think it would be feasable to use it as a calculation to figure tier rate. The tier rate calculated would not take into account the difference between single-prim sims and double prim sims. Using your example of US$1,250 all 5 of our SIMS would be taxed to our citizens as $250.00 each. That would result in the problem we have now with such a variety of tier per rates. An excellent idea for budgeting but not for setting of tier.
Now I'll address the issue of single prim vs double prim and and setting tier rates based on PRIMS vs. SQM. In my report I used the United States Dollar as the control of all pricing because that is how we pay LL for our estates. Whether the rate of exchange is 256lindens or 285lindens we are still paying LL US$295.00 for a full sim, that is the constant. We can base our tier rate on prims but first we must establish that control mechanism which needs to be the per sqm rate because that seems to be the standard in Second Life. Once we establish that control than it's just a matter of simple mathematics.
In US dollars a full SIM costs $295.00. That is a cost of $0.0045013427734375 per sqm (295/65536) which is the same as a cost of $0.0196666666666667 per prim. (295/15000). So where is the difficulty in the pricing of a single prim SIM and a double prim SIM? Linden Labs charges $295.00 regardless of whether the land is single prim or double prim so your control is the per sqm rate. Even though you're allocating double the prims the amount of sqm stays the same. That's why there is an increase in cost to a citizen for a double prim parcel but not quite double the amount of a single prim parcel of the same size. I will point out that if you look at the sheet titled Tier Charts in the top left corner is my proposed new tier structure for original 5 SIMS* the difference between single prim tier pricing and double prim tier pricing is very close to double. Look further down to proposed tier structure for all new SIMS for the CDS the difference between single and double isn't as near to double but is still a considerable amount.
Now I do believe with the Hippo system you have the capability of assigning how many prims goes to each parcel. If I am correct than this would be an excellent way to make available extra prims for a monthly fee to an interested party as long as the publicly held land had a surplus available. For example in NFS I believe we have what is referred to as microplots that are plots citizens can purchase for extra prims. We'd turn those microlots into publicly held land and than allocate the prims to whomever wants to rent them on a monthly basis (no different than currently paying tier but they're paying for prims instead).
Fern I have punched in your numbers into my spreadsheet and I will send you a copy of the workbook with that sheet in it. It's titled Fern's Proposal and is the last of the worksheets. Using your suggested rates of L$ 1.77 for single and L$ 4.25 for double, based on the CDS parcel lists in my report would result in the following.
NFS no increase or decrease in tier
CN decrease in tier of US$ 75.82
AM decrease in tier of US$ 40.56
LA increase in tier of US$ 79.80
MON decrease in tier of US$ 95.48
Total Savings $132.06 or about 8%
Again this empasizes the unique situation we have with the original 5 SIMS and the way they are parcelled out. That is why I proposed a set rate for NFS and CN that are the same, another set rate for AM and LA which are also the same, and than just an entirely different scenario for MON due to its unusual situation. All future SIMS brought online wouldn't be this difficult to price out. Here is my savings based on these proposed rates.
NFS decrease in tier of US$ 25.30
CN decrease in tier of US$ 112.97
AM decrease in tier of US$ 182.09
LA decrease in tier of US$ 56.96
MON decrease in tier of US$ 19.16
Total Savings of $396.47 or about 23.3%
I'm going to end this post for now, I have a midterm this week to study for. I will address other points of interest in my next post along with any new ones added due to this post. I look forward to any and all feedback.

******ATTENTION I had to edit this document because for AM I accidently put in the public land of 37,888sqm as the sqm of privately held land and NFS private land is actually 37,168sqm which is 56.71%. The correct amount of privately held land in AM is 27,648sqm which is 42.19%. Any calculations in this posting have been recalculated if they were affected.********
