Eh ofc u work up to it
Perhaps once you hit RPE9 you could try it again to see if that was a true RPE9, then lower 5%
that's a bad idea but that's why you should know how to gauge RPE before attempting this type of training.

What if I get the wrong RPE?
One final issue that I want to address with RPE is that of overshooting and undershooting. In other words, if you’re prescribed @9, and you go to @8 what should you do? What about @10?
Undershooting
If you undershoot a full point on the RPE scale, you should do another set. That is, if your top set is only @8, do another top set with a bit more weight.
If you get within half a point, that’s acceptable. In other words, if your top set is @8.5, don’t do another set.
Overshooting
If you accidentally go to @9.5 or @10, you definitely need to stop there. If you are in the middle of a set, I would always recommend trying to get the
prescribed reps unless your last rep was @10. I don’t want you to purposefully fail. I do want you to try and get your reps and then measure RPE after the fact.
Back-Off Sets When You Get the RPE Wrong
If you undershoot or overshoot, the major implications are on your back-off sets. For your back-off calculations, use the weight that you think you should have
used to get your original prescribed RPE. While you can bust out the calculator and figure everything out, I’d recommend just using common sense.
Let’s say you were supposed to get @9 for your top set. If you got 405x3@8.5, take your %s off of 410-415 or so instead. Do back-offs until @9 as you were prescribed.
If you got 405x3@10, you’re going to need to make a bit more substantial adjustment. In this case, you’d probably want to base things off around 385-390 or so.
Again, you can calculate all of this precisely with the RPE Chart but you should be able to get close enough just using your best guess.
