Archery speed tests for 4.2 standard shot - new dex break[]
Results Tests below in reverse order. Number on the left is dexterity, number on the right is shot speed for 4.2 standard shot with 10% archery speed (casting speed = same as archery). Note - there is some variance because the parser only counts to the nearest second, plus server lag. This means that tests for the same dexterity will have tiny variance.

414 - 1.69 (odd variance)
415 - 1.72
473 - 1.71
473 - 1.72
So the new dex objective for archers should be 398.
It'll give you a roughly 3.1% archery speed increase over 392 for standard shots in version 1.121.
