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.) :)
I also believe that the pool does not have to be “exactly” 25 yards or meters. I know there is a +/- factor (what that is I couldn’t say). But I also realize Jim might have just been saying exactly 25 yards for the sake of argument. Not sure that a quarter inch is outside the margin of errors not.
FYI, the USA Swimming tolerance for length is -0.000 / +30mm (1-3/16").
(I'm working on my Meet Ref certification and was just going though all this stuff last week).
There is a pretty detailed and comprehensive procedure for measurement and certification by a licensed engineer or surveyor.
One of the potential problems is that there is no requirement for periodic recertification. Things like changing brands of touch pads or resurfacing can affect the measured length.
With regards to movable bulkheads, one of the interesting requirements is that the lane lines be in place and tightened prior to measurement.
