I'm not certain, but I think you're asking if you can spot when a vp game with a progressive meter on the RF becomes positive. If that is indeed the question, it is fairly simple if you are already familiar with the base game. If you're not, you probably shouldn't be playing it anyway.
For example, a rule-of-thumb for a JOB game with a progressive RF is to add 0.5% in expectation for every 1000 coins the RF is above 4000. Of course, that increase in expectation assumes that you also employ the proper strategy changes for the amount of the RF, so you need to know those points. If you don't, you can trim your estimate for the increase in expectation a bit.
Any vp software will allow you to manipulate the value of the RF for any game to see how that affects total return. Most will allow you to see strategy changes as well for different RF amounts.
You can also expect an increase in variance as the RF value increases. Part of that increase is due to the added value of the RF, but some is due to the strategy changes which cause you to bleed money more quickly until the RF shows up.
