Backfilling ramp up sets?

Given a prescription of 6@6, 6@7, 6@8x3:

I’m warming up as recommended by doing sets of 6 up from the bar. Say I hit what I think is a 6, add weight to hit the 7, but it turns out to be an 8. Should I do 3 sets and stop, 3 sets and then drop 5% and do another set to get the @7 one I missed, or something else? Since volume 7 or above is counted I’ve been doing the latter but just wanna be sure.

Thanks as always for everything

If you’ve been doing 6s all the way up, I’d do the three sets @ 8 and stop, then do better next week.
