Early game imporvement is relatively noticeable but it diminishes significantly as game progresses.
I am calculating effects for new positive speed bonus mechanics not for vanilla negative recovery bonus mechanics.

Early game imporvement is huge due to low combined damage at the time. End game improvement is still quite significant.

Similar to attack bonus the effectiveness of AC bonus falls even more drastically toward the end of the game.
