M-ratio

noun

A measure of the health of one's stack: the stack divided by the sum of the small blind, the big blind and the antes of each player. The result (M) is the time (the number of orbits) it would take for one's chips to deplete if the player only passively places their forced bets and otherwise folds.

“M=(mbox stack)/(mbox smallblind+ mbox bigblind+ mbox totalantes)”
