It varies.I know bad answer but....
As far as reducing my own plays by 50%. Doesn't happen. If I see a good play, I'm on it. Not cutting any plays out. Too much involved in finding what I think are good plays. Now, if I've been crashing and burning lately, I'll just stop completely for a day or two.
If I do cut back on any plays, it would be on the plays that I might make to tail someone who's been hot. Those get cut if I want to reduce number of plays I'm making. But, I've never tracked if that was a good thing or bad thing.
