It might work every once in a while, but in the long run is really bad math
All plays should be +EV, then the math isn’t so bad.
I know many who argue that you should pound the +EV you can get, be thankful you got it, and never sell any back.
I can appreciate that, but sometimes the EV is big enough to sell a portion back in the LIVE markets to keep stability in the business and to mitigate the effects of variance.
This has worked for us for a long time now.
