The T key is really only useful to select targets with. It gives a rough idea of the percentage to-hit chance for the slot 0 weapon - which may well be a wild gunners overestimate it seems, sometimes.

The only accurate to-hit percentage is the one shown on the top info line when the weapon is actually fired and all the "dice" have been rolled. That may be rather different from the "T" key guestimate.

If it pings and pongs about then you probably are on some sort of "edge" condition, is my guess.
