I believe - but I could be hallucinating that 50% quickness is intended to give an attack every other round.

Attacking is supposed to consume your full AP; it is supposed to put you into negatives. The negatives are then supposed to carryover when your AP gets refreshed the next turn.

Rather than being a bonus of 50% to your ap each turn, is there any chance they are giving a full bonus every other turn? I think this might better explain the behavior you observed.

Additionally, haste doesn't give a ap increase Idont think - I think it decreases the cost per square to move - for example, from 4 to 3.
