Everything the
monkey said.
Fwiw, I find I play much better without a
HUD. That's because I find myself looking for a stat to justify making the decision I want to though, rather than using a combination of
stats that would more likely
lead me to the correct decision. The
sample size is the biggest problem and it really is important to understand what the
stats mean e.g. if
villain is raising 15% of flops over a large sample, what can we infer?
There's still no substitute for
notes imo too. Most villains at the micro stakes have huge bet sizing and
timing tells and rarely vary their lines e.g. when they bet a wet
flop they have something, otherwise they
check fold. Just looking purely at a cbet stat won't help you in those spots.
