Yes it's pretty accurate. It only applies to sngs so I doubt people would sharkscope you in a cash game or mtt as its is not applicable. OPR is for MTTs and now includes SNGS on full tilt only I believe.

I asked if you were serious because think about your question.

Why would people lose alot to have bad stats to fool people so they were getting a slight advantage. That would make no sense and would result in net ----EV. You don't purposely lose alot of money to hopefully later make a little money.
