more "pumped" = better workout?

During and after a PE workout, is bigger always better? Is the amount your pecker is swollen the barometer of a successful workout?
I’ve read Avocet referring to “less is more” on more than one occasion, but I don’t recall ever reading a thread where guys here debated how much “pump” is too much, or if there even IS such a thing as too much. It seems that most here PE under the assumption that as long as it’s not lymph fluid and donuts, the more swollen you can make your cock from pumping/jelqing/squeezing, the better.
Give me an hour and I can easily uli & pan squeeze myself to a full inch bigger in girth, with no signs of donut swelling. And I did so very regularly for several months, but saw zero girth gains in the end.
Lately my approach to PE (girth, specifically) has been built around the assumption that this isn’t true. I can’t say that my new approach has suddenly turned things around for me… it’s still way too early to tell.

How do you guys see it?

Just to clarify, my suggestion that “less is more” refers to time spent within the cylinder in one pump session, not to the size you may get pumped up to during a workout. Short pump sets each lasting 6 - 8 minutes seem to give better long term gains than staying in the tube for, say, a half hour or an hour at a time. This probably has to do with the more frequent exchange of newly oxygenated blood.

If you end up a PE session more pumped up than with a normal erection, that’s good, imo.
