14 Amp tool on 100' 10AWG extension cord? (lemm.ee)

I have a 14 Amp Ryobi miter saw. In the manual it has a table for required AWG by Cord Length and Amps. For 100' and 12.1-16.0 Amps it just has a dash indicating there is no suitable AWG extension cable for this length and amp combination.

However, protoolreviews indicates 12 AWG is sufficient for 15 Amps and 100', but 10 AWG would be safer. https://www.protoolreviews.com/extension-cord-size-chart-wire-gauge-amps/

Is protoolreviews correct and I can get away with a 10 AWG, 100' extension cord for my 14 Amp tool just fine?

I know if something goes wrong it will likely be on me as Ryobi will point out I didn't follow the manual.

How much cutting are you actually going to be doing? This is going to be key. The resistance on a smaller wire (larger gage number) and longer length is going to turn the cord hot. But if you're making 3 cuts, I wouldn't worry about it. If you are going to run it 24/7, then I'd worry.

I'll definitely be using it lightly. If I was cutting 24/7 I wouldn't have gotten a Ryobi.

Run it for a few days at the expected use amount and keep an eye on the heat of the cord but also the outlet and plug. I do have to say that 100' is a lot. No outlets closer than that to you?
