In the Stars! User Guide there is a formula for calculating resources from an AR planet:

Resources = Habitability_Value * SQRT ( Population * Energy_Tech_Level / Efficiency Coefficient)

However, this formula does not work for planets with a negative habitability factor.

For a race with a single immunity the actual habitability factor to use is 25%, so the formula needs to be modified. If using a spread sheet you could use something like:

Resources = IF (Habitability_Value < 25% THEN 25% ELSE Habitability_Value) * SQRT etc... as before.

It is possible to make a spread sheet using the P file from the game. If this is opened in an Excel workbook as Sheet2 then the resources for each planet can be shown on Sheet 1 using a formula such as this:

=IF(Sheet2!F2<25%, 25%, Sheet2!F2)*SQRT(Sheet2!E2*Sheet1!D$1/Sheet1!B$1)

In this example, which looks at the second row (the top row being a header) D1 on Sheet 1 is the current Energy Tech level and B1 is the Efficiency coefficient for your race.

Sheet 2 is the P File but sorted by Planet Owner. For simplicity you could delete all other planets except your own.

If you paste this formula into the sheet for every row you have a planet and total it up it gives an answer within about 1%. You can then see what the advantages are of researching more tech or moving populations around etc.

I have not tested this for a Bi-Immune race but I assume the factor would be 50 not 25%? I have also not looked at what the formula should be for a race without an immunity. Any suggestions would be welcome.

Update: Have just tested it with both a Bi-Immune race and a race with no immunities and the minimum habitability factor remains at 25% for both races.

We already knew this. How is this news? Confused

It was news to me - it is not in the User Manual and I could not find it in the Wiki.

Always good to know and especially if it's in the right subforum xd.

Edit - ah, this should be shifted to the AR subforum Very Happy.

The main "library" is still the old r.g.c.s. Usenet newsgroup. Lurking

I can't find anything much on that link about Stars. Do I need to subscribe to something?

I'm sure this is probably well known resource, but here you go:

www.starsfaq.com

Includes "RGCS Advanced & Technical FAQ", old StarsFAQ articles, and a wealth of categorized articled from an old Omonubi's site "Stars-R-Us".

I learned all I ever needed about playing AR (and other PRTs too!) from these articles.

Thank you - the 0.25 minimum hab value is mentioned but I must have missed it as it isn't actually shown in the formula itself. Which was why my version of the formula had the "IF" statement.

What I am still trying to work out is a (ideally) simple way of predicting the populations on starbases in the future so it might be possible to have a spreadsheet which could more accurately predict future resources.

The formula:

present pop + ((growth factor * present pop) * (1 - (present pop / starbase max pop)))

Gives an answer for the following year to within about 5% for the tests I have done so far but I need to test it more to see how accurate it will be for say 5 or 10 years in the future.

?

Someone else gave me that link before but I already have the Stars! calc but that is not what I am after - I am looking for the formula for calculating future populations so I can put it in a spreadsheet.

have a read around for general pop growth formulas....apart from the SB hab sizes, ARs aren't really any different from any other race. The complicating factor is thwt Stars! calculates pop to th nearest person (IIRC) but only displays in 100s.

Thank you, I will have a search, but if I can predict future pop to within 100 that will be fine!

Keep scrolling "down" past all the spam it has received in recent years. Even better: use the "search" functionality. Lurking
