[Star Trek] Why can't the Borg pre-emptively adapt?

So generally in Trek, the Borg adapt to weapons frequencies, rather than the weapons themselves; If they get damaged by a phaser shot, they adapt to that phaser frequency and then you can't use it again. But why can't they analyse the weapons frequencies they've already been hit with, think "Well, the enemy will probably use frequencies close to this one" and adapt to those as well before getting hit.

It actually takes the Borg quite a long time to adapt to just one frequency. Changing the frequency by 1 Hz is a completely new threat to deal with and would take just as long to adapt to as the original frequency. 1 difference is nowhere near the original and has to be recalculated from scratch completely. The range of frequencies that can be used is massive, to preemptively guess which ones would be used is hard. And anyway, the modulating frequency usually jumps around the scale by quite large intervals.
