That's what thermostats are for, eh? :-)

With low-mass emitters like fin-tube you're not going to get a monster temperature overshoot with just 2x the min radiation required to heat the zone, and if you did a T-stat with tweakable anticipation would usually fix it. With excess high-mass radiation you may have to resort to smarter PID algorithm thermostats if the radiation is grossly oversized & very massive, but that would be a huge boost in comfort too.
