Yes this post is not nearly as important as the one on playing under-rolled (see link at the top).

The point essentially (now I read back through it) was that if you have enough so that you are rolled for the next level (where "rolled" implies your indifference over gambles with the same EV and means you are NOT risk averse), it is mathematically incoherent to remain playing at your current level.

Well done for finding it
