BTN vs CO calling statistic

[shawnallen]

I am interested in the statistic for how often the BTN calls the CO raise. I was able to do this for 3bet by going to the statistics tab, grouping by position and adding the statistic '3Bet vs CO 2bet' and looking at the appropriate entry. However there I see no analogous statistic for 'Call vs CO 2bet'. What is the best way to proceed -- by creating a new statistic?

Yes that can be done with a custom statistic - see this guide for the basics on custom statistics creation and this guide for a deeper walkthrough. While the latter was written for PokerTracker 3 and the user interface is different the techniques still apply to PokerTracker 4. There may also be some examples if you search this forum or the Download Warehouse and you can edit them if they are not exactly what you are after.

Thank you, I would like to create a statistic. I am new to the process and trying to understand how the 3b vs CO 2bet statistic is made. I understand that it is of the form (cnt_p_3bet_vs_co_2bet / cnt_p_3bet_opp_vs_co_2bet) * 100 and that this is the general form of a statistic. When I look at the column cnt_p_3bet_opp_vs_co_2bet I find the following:
sum(if[cash_hand_player_statistics.flg_p_3bet_opp and cash_hand_summary.str_aggressors_p LIKE '81%', 1, 0])

I understand that the first term in the if statement is basically asking 'did this player have an opportunity to 3b *at all*', but I don't understand the 'cash_hand_summary.str_aggressors_p LIKE '81%'' phrase. Presumably it is capturing that the RFI came from the CO. Could you please explain what this term is doing?

That's testing the preflop aggressors string which is a series of numbers that records the positions of the players who raised preflop in order. The aggressors string always starts with the BB position (8), the second number is the position of the player who 2Bet (1 is the CO), the third number would be the position of the 3bettor and so on. This post has more information on how the aggressors (and actors) strings work.
