You are drawing the wrong conlusion here.
If there is any movement whatsoever between the reel and the motor shaft in
servo tension controlled tape machines such as Ampex ATR102 and the Studer
A820 then the servo will misbehave badly.
The mash down NAB adaptors used in the ATR102 will see to it that the
plastic reels are securely bonded to the reel motor mounting plate thus
there will be no movement between the motor shaft and the actual reel.
Thus reel weight has nothing at all to do with the observed misbehaving of
the ATR 102 servo system.
