you'd have to do some research on this... individual choices for local contracts can severely impact what you see vs what someone else sees as a result of team interest and such on income.

Effects on media income:

i'd do a min / max fan loyalty for each market size relative to fan interest and the other settings you want to control... then whatver points you want to test in between. go to team settings with commisioner mode on... input the vales to test... go to Front Office -> Accounting and check media values (must deduct national media contract* from value on this page - not itemized here). make a not of it on some paper or better yet use a spreadsheet for easier analysis once done collecting data.

that will tell you how much fan interest and loyalty affects income for each market size... changing a fan interst of a 5 market +10 will not have the same effect as adding +10 interest to a market size of 10. good stuff to understand if you want to manipulate it based on knowledge as opposed to blindly doing it.

If i recall: default financials... a 5 market may range 10-15milion in local media per year based on loyalty and interest. a 10 market size may range 20 and a 14 ranges 30... making this stuff up a bit to show you cannot assume what happens at a market 5 is not the same as other sizes. you will have to test each size. once you know how each works yo won't have to worry about it as much with gate revenue becaue you already understand its effects.

MOST importantly, effects on gate revenue:

Attendance income is the other part to this... a bit more complicated because the estimates for this stuff really suck, even more so in year one of any league i've seen. this may require you to sim out to test various fan interest and loyalty settings. plus you don't have equal capacity at each stadium... demand effects price i would assume, but i think a larger stadium stil makes more money (althogh if you go too big it hurts eventually - e.g. 54k stadium vs 80k stadium with same ticket price ... in the past the smaller "big" stadium would get a larger attendance, ceterus paribus. if dodgers stadium is largest in league, don't worry about this much)

use a backup... find teams that are successful, .500, and poor and see the results fo the various levels of intersst and loyalty on gate revenue. what is crappy here is stadium size. you'll also want to know a bit about how the AI sets ticket prices.

just understand all the effects for all the situations and you can put together somethign that will work well almost immediately... somethign like this may take tweaks even if you think it through first...
