Thanks for looking into this naive question. I have found the answer. The min raise is always equal to 1 BB. Min Raise amount = Call amount + Big Blind amount

In all betting rounds, the minimum raise is the amount of the previous raise (or opening bet if there have been no previous raises). In the first round only, the big blind is considered the opening bet if it is equal to the game's minimum. If the big blind is smaller than the game minimum, the the opening bet is the first bet of at least the minimum.

So, scenario 1: \$20 BB was the opening bet, so the minimum raise is another \$20, making \$40 total. Since you have \$10 in the pot, you must add \$30 more to raise.

2: Opening bet was \$20, there was a raise of \$20 more to \$40, you must raise at least another \$20, making it \$60.

3: Essentially same as #1. You must raise to \$40, but since you had no money already in the pot, you'll have to put in all \$40.

4: Initial bet was (your) \$20, SB made it \$40, your re-raise must make it \$60 (and since you already have \$20 in the pot, you must add \$40 more).

Your software was correct in every case.
