I don't think there is any quality control at the Smarties factory. I have counted as low as 46 in a pack up to 57. Would it be weird to take weigh the smarties packets on the scales in the fruit & vegie section to see which have the most inside. Yes, you are right that is a bit extreme. Instead I give the pack a shake & the one with the least shaking space is the 'winning pack'. That is how I found my 'PB' of 57 after my previous PB was only 53. The day I only got 46 I was ready to riot!
Maybe I have too much spare time ...
