shotgunning is generally used by people who are looking to win the competition circuit. for instance, in my state, we have 6-8 competitions from which you get points for each medal, BOS, etc. and at the end of a competition season, there is an award for Brewer of the Year for the state, as determined by the points. There are people here who enter 30+ entries to a competition, That's $180 in entry fees alone!!
I could care less about that kind of stuff, so I don't bother entering more than a handful of whatever is on hand at the time, but a lot of guys here get into it. I tend to look at my percentage of awarded entries as a better barometer of whether I'm doing a good job or not.
In fact, I think that would be a better way of judging for BOTY, your 'hit' rate with some weighting toward 1st, 2nd or 3rd, BOS etc., with a minimum number of entries to qualify, rather than just an absolute point total. It would reduce shotgunning
