A knock-out isn't a hard strike to throw Hermes, and you can't tell where Luffy's devil fruit ends and he begins due to it's very nature now I put it at a conservative 10 as that;s a fair number for him and a safe number to go from as his strength may well be linked with his fruit as he hasn't been shown (atleast to my recollection) excersising, or strengthening himself. His physical strength will share it's roots with Gear second and Third through manipulation of his bodies structure and shape however sub or fully conscious a reflex it is.

I repeat he had it since he was a young kid, barely more than a tot, it seems based on the timeline flash backs he had it before his training with Dodon (thats her name right?) as at that point in time he had his hat. Having it his entire life without it he just can't fight...now he does seem resilient without it as shown by BB in ID but I'm skeptical...okay let's up it to 30 to be fair.

P.S. A reindeer won't up it that much. Gun vs A reindeer? the head mounted on a plaque in my garage will tell you a tale of who is stronger.
