...or...you could just get the youtube adblock/sponsorblock skip extension (dunno exactly what it's called SkipAdTrigger or something? I cannot check my home machine at the moment...but it's available for Firefox and I'm pretty sure something similar must exist for other browsers as well).

Works well in my experience. It automatically skips sponsorblocks and marks them as green on the time bar (so you can manually watch them if you're into that kinda thing. Hey, there's all kinds of kinks out there. Don't judge.)
