This is not meant as a criticism. How does this drive the creation of a new sport? It just makes accuracy more of a factor. Either you will shoot better or shoot more. At most wouldn't it drive you more towards USPSA where more shooting is common?
As to the age differential, as a hack shooter I am fine with that. While I haven't seen such to that great an extent whats wrong with a shooting sport with more average folk in it?
IDPA, ICORE, 3Gun, Steel Challenge were all created due to perceived failings of IPSC (and later USPSA) to address their customers wants and desires. Accuracy already is a factor in USPSA and was a bit more emphasized in IDPA. Taking it to 1s/point make accuracy the factor and makes speed a side note. Speed IS a tactic and getting hits ON TARGET at speed is a huge benefit in a "real world" encounter. But, alas, this is a game, and not even close to real world, even though IDPA is attempting to dress the rule change in those clothes.
USPSA is more competitive and faster, and you do shoot more ammo. We have some competitors locally who shoot IDPA for those reasons. A 70 round match costs them half what a 150 round match costs. For the few times a year casual shooter, IDPA is a greater draw, and I get that.
My comment on the age gap was more of a wisdom thing. I might be old fashioned, but the old farts have a deeper understanding of the history and a 20 something squadded with a 60 something stands to learn something. Drive the youth away, not only may it kill the sport long term, it will kill the passing of wisdom and knowledge that the old farts gained in the same way.
So if IDPA is too slow and USPSA is too equipment driven, IDPA just opened the door for the creation of a middle lane. Which again, might be good.
