SSB target wattage increase?

Ok so let’s preface by leaving out any discussion of FTP and testing, we don’t need to rehash any of the many current threads on that lol

If someone has recently done an hour averaging, say, 272w and is now in SSB hv where intervals generally tend to reside around 90%, and that also happens to be about 272w, would they benefit from upping their percentage a bit for a little more stress to adapt to? That is to say if one can do an hour plus, is there any benefit of going backwards and doing intervals at the same power? I guess this is kind of a reverse of the sweet spot progression thread lol
