not so much now that I have retired, in fact, none, but nails, screws, staples were a regular thing for me, using my bike as a company vehicle, going to jobsites, punctures were a regular thing, usually in the first 500 miles, so I can safely say I have ridden well over 100k miles on plugged tires, (rope plugs from the outside)
I even stuffed 4 plugs into a tear in the sidewall of my yard truck, held air for 5 years till I junked the truck, in the meantime, it only got rough terrain offroad use, I never trimmed the plugs, they stuck out of the tire's sidewall like whiskers
