Be careful with HUD stats in micro MTTs (I assume you play micro/low, no malice intended if this is not the case).
You need a big sample of
hands to have reliable stats for decision-making and micro stakes simply will not give you that, because you will not come across the same players often enough, depending on your volume (multi-tabling), their volume, specific stakes (at low stakes on
pokerstars you might get decent sample sizes on opponents), etc.
Therefore, I would stick to basic stats that converge quickly.
Most important: VPIP, PFR, 3bet preflop & Aggression Factor/Frequency.
Important: Preflop Limp, Preflop Limp/fold, Cold Call, Attempt to Steal, Fold to Steal.
Also have positional breakdowns for all preflop stats above.
Postflop: Fold to Flop cbet, Cbet Flop, Went to Showdown (WTSD), Won at Showdown (WSD).
Postflop stats take very long to converge so be very careful, depending on many factors they could be useless.
Turn and River stats converge too slowly to be meaningful: huge samples needed for them, as well as WTSD and WSD.
Also, filter your stats per number of players at table and/or stack sizes.
Having said all that, you will only need VPIP and PFR to get an overall feel for your opponents, which is enough to win micro tournaments with fundamentals and solid play.
