Just playing around with numbers and inputted the following……I'm sb with 3750 and bb has 1500

pot                        600

your stack            3750

BB                        250

Effective Stack      1500

Single Call Range  41.00%

Left to Act                 1

Win %                 29.00%

And then I get

If we shove and get folds          4350

If we shove, get called and win  3600

Surely if we get called and win that should be 5250. Obviously I'm missing something, do I have to do something different for blind v blind? Thanks.
