What does the statistic 'my c all in eq adj' mean

[glyn]

in normal speak?

[kraada]

It means:

Amount of money won in the preferred currency set in PokerTracker when adjusting all-in pots. In those pots instead of attributing real results, this statistic attributes to the player the equity they had in the pot at the time of the all in. Pots where players call the all-in bet or raise but later fold (hence their cards are not known) are not adjusted.

You can find detailed descriptions on any stat in the Configure -> Statistics window.
