Outbreak,
Kyle explains that for most it is easy to nail two fast shots. It is a whole nother thing to be able to keep dumping those shots in the same place very quickly. What it in essence does is exposes weaknesses in technique. Even though I have been shooting from both shoulders for years - THIS drill has been the only drill I have run that graphically showed the weaknesses I have with my left side shooting foundation.
I can get two shots off pretty fast left handed. However - I have never tried 10. And as you can see - my left side is not able (at this point) to keep up with my right side. This shows me that my left side needs a LOT more work/attention/training than I thought it needed.
From the 20 and the 10 I *smoked* the times right handed. I went overtime and had 1 miss left handed. If I would have just shot two rounds - the difference wouldn't have been that dramatic - and I wouldn't have had a miss either. Both my misses left handed were around the 8th shot (from the 20 and the 5).
In other words - I *thought* prior to shooting this drill my left hand performance would have been MUCH better. However this drill gave me SIX helpings of humble pie. One for each overtime string (3 left handed - 1 right handed from 5 yds) and one for each miss (1 left handed from 20 and 1 left handed from 5 yds).
To me that is benefit of this drill - it shows me my weakness where I thought I wasn't so weak.
cheers
