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.) :)
ForceDJ,
Pools or courses that do not include moveable bulkheads only need to be measured once (each lane of the course) or after a renovation that includes the tank or gutter systems. Another problem with moveable bulkheads is the "pinning" mechanism. Over time, the holes where the pins fit do wear and get bigger. These pools are built to be as close to the minimum legal length as possible, so even a small amount of wear can be a problem.
And, there are other systems that do not include pins - sometimes just the weight of the bulkhead itself resting on the bottom or on the gutters. These are subject to stressors that move the bulkhead thereby affecting the length of the course.
Lots and lots of variables which makes the measurements important. And, finally, a masters national or world record can be set almost anywhere and at any time of the year. I set my SCM world record in a little meet in the middle of May - only 2 people in the event. Luckily, the pool did not have a bulkhead and had been measured. BUT, it would be very sad if record swim was done and the pool was too short. because someone decided not to measure.
