revenues will look different for sure. the percentage can be applied to any historica or fictional settings.. tehy simply morph over time. (i would hope it's robust enough to work with historical play) i should still take any new value and simply multiply (1+%)^t (t=years). just because it's a historical value and not a stock value doesn't mean they can't apply the interest to it relative to your start year... i hope, because you don't need to know how to code to do it
you don't have to worry about settings auto-changing on you... once you have imported or set what you want, make teh 'historical year' post-2018 and nothign can import. thats in STats and AI... and, not the actual year of league, no worries.
you may need to apply the coefficient check box. that will reduce the values below 2^32 (signed). no problems with large numbers that way, and visually it all looks the same to you.
if you think you can predict future inflation of MLB with any accuracy beyond a wild stab in the dark, you should go get an honorary economics degree. good luck with that. don't get hung up on trying to make it like 2019 or 2020... no one has any idea and if they say they do it's a ballpark figure or a lie.
max cash on hand? that's a good question that could answer itself within 1 sim year. i don't believe that value changes. it stays in proportion if you use the coefficient due to large numbers, but the value stays the same from what you see. if not, it'll also bump up a bit each year, but that has potential ramifications they may want to avoid.
too much max cash on hand is a bad thing over time, fyi... well, depending on your preferences of course. since it would stay in proportion, that wouldn't be a problem from infaltion, i guess. but, definitely keep a cap even if it doesn't keep up.. change it manually if you want to give a little extra.
cash on hand is completely unnceccessary... if you want 10M more profit, add 10M to revenue, etc. it doesn't really provide any benefit and it definitely has a drawback in some contexts:
FA - FA wil be inevitably cheaper than the extensions they demanded earlier in offseason. cash on hand can be used for extensions, but not FA contracts... hence WAY more money for extensions than normal after just 10-20 years. the teams that are successful early on will build up a huge pot of money. billions of dollars over time.
so you never sign and extension and always wait for demand to drop to earth... but the AI isn't that smart, is it... they will be spending way too much on extensions operating under the typical trend that FA is more expensive than extensions, more times than not.
the overflow problem is fixed by the coefficient. no big deal for a large value now.
short and simple:
it does crazy stuff to your money supply which effects demands of players blah blah blah... if that's okay, go for it.
