No, it sounds good. Diffrent manufacturers may vary the "turns" and ultimatly the Resistance a bit, but that resistance sounds good. That higher restance is small, but may result in stronger secondary due to a 'higher saturation point". When a resitance drops in a winding it is usaully caused by a breakdown of insulating material and effects resistance values. If that value drops enough, the output will drop porportionatly.
I have checked coils that tested 'good'. - Well in spec, however in operation they would not function properly. Once a load was introduced, the "short", or very low resistance had the effect of dropping secondary voltage beyond useable values. I guess what im trying to say is simply that coil readings can be misleading sometimes, so the ol eye test is a relevent one. If the spark is blue-white and snaps, I got a good coil. If its orange, chuck the coil............. :P
