Agreed. Isn't it at least 10 minutes of riding before the plugs even reach applicable burnout temperature? Or is it less?

Something like that. Depends on the engine and the mods, but it can easily be 5 minutes if it's 85 outside and 15-20 minutes if it's around 40 (F) outside.
Common mods:
Ignition advancer: gets to temp faster, runs hotter.
Jet kit: runs richer, but cooler as a result. Takes longer to get to temp.
Irridium plugs: gets to temp slightly faster, burns off across a wider range.

Old/partially evaporated fuels will also generally burn cooler because the lighter compounds are gone, meaning it takes longer to hit full operating temp and fouling is far more likely to occur.
