Within CVBJ, under the Heat Index Options, Norm has the heat index as follows (excerpt):

Bet > 25: 5
Bet > 90: 12
Bet > 240: 15

My question is this: If the previous bet = 100, but the new bet = 250, does this lone new specific bet (250) heat index total 5 + 12 + 15 = 32 ??? ... or does it only total an additional 15 to the previous tally which may or may not include the previous 5 + 12 depending on what the minimum was ?
