Nope, Droopy. Acceleration works different. It's like saying 50% speed for Krow means it's 50% weaker and that would be true.
HP, Cost, max speed, range, damage and similar directly reflect a unit's strength.
Acceleration, line of sight, collision volumes, accuracy, steady E costs, etc. are all something special.
The first only affects a unit for short times, los is shared, colvol only applies when firing with low accuracy/at radar dots, for accuracy see colvol and E is some sort of tech that gets cheaper as the game progresses.
