Please forgive me for this, but my OCD brain needs to know:
When they put that barrier in the 50m pool to make 2x25m pools, how can you be left with 25m if the barrier is at least 1m wide?
(This matters to me, sorry.) :)
Put me down in the camp that considers the USMS measurement requirements ludicrous, especially since "hand timing" is still legal, and it's virtually certain that there is much, much more room for error in hand timing than there is from pools that are an inch or so off absolute kosher length status.
Wow. I didn't realize that, either. The allowance of hand timing does make the strict adherence to length seem hypocritical. I was considering what Windrath suggested about that fraction of time over the length of a 1650. That comes out to 0.230 second (less than one-quarter second) per 1650 (Well, at least at the 100y pace suggested above). Obviously it is "measurable." But handheld/manual timing can error that much. Ridiculous!
Something else I was just thinking about bulkheads, and how the tightness of lane lines causes them to bow, and creates inaccurate measurements in the center lanes. My question is...if that is caused by the bowing of the bulkhead which is placed in the center of the pool...can't it be corrected by tightening the lane lines in the 'other' pool to take the bow out of the bulkhead? Instead of just mooring the bulkhead at the sides of the pool...seems like there should be a mooring, or two, to the bottom of the pool so that it can't bow when lane lines are tightened.
