I looked on the rules there is no such rule for a legal minimum number so they made it up. My motor comes off at 21.3 each terminal. Its a good thing to know the rules and make sure the things you are running is legal. Also what motor are you running that has a 20.0 ir?

As far as it being old, it all depends on the abuse it has endured. Multiple classes, or every weekend is abusive regardless of temperature. Think of it like a car motor, the more miles the weaker it gets.
I have a friend whose D3.5 now has brown wires from being at 160*-200* on many occasions, it still runs great but it does fade substantially into a run.

As of today, the Trinity D3.5 10.5T, 13.5T, and 17.5T are no longer ROAR Legal motors, so if you plan on running ROAR events, I would suggest replacing it.

21.1 is the ROAR minimum for IR of the stator, my Trinity Revtech Maxzilla is 21.4/21.4/21.3 and I race with a guy who owns a Big Blue Bad @$$ which is a Big blue can and 13mm rotor, and i pull him in RPM, but he gets me in torque because of the rotor. The BBA is only legal in outlaw and mod classes, but at our club races they dont tech motors.

The list can be found here. The D3.5 is still listed from 3.5 up to 10.5 but no 13.5 or 17.5 is listed.
