yeah I'm gettin 100 grams everytime when I have all 20 nickels together but when they're in groups less than that there are discrepancies...I just don't get this.. every individual nickel weights 5.7 but together they make 100 on the dot I just don't get it.. and yeah I mean obviously all 20 together is gonna make 100.0 since that's what I'm using to calibrate but even so how is it that when I take exactly half (10 nickels off) I get a reading of 56.4 and with 5 nickels on I get a reading of 28.1...

I am just completely thrown off and I consider myself pretty intelligent...
