lane ropes and tile markers worth 1.5SPL?

[andyinnorway]

I'm swimming in a resort pool all this month which is 27.4metres (30 yards)

Everyday of the week my benchmark test SPL settings are tt1.26 SPL17, this is the same in any 25m pool I go to in a typical public session

In this month's pool I am struggling to hit SPL20, 21 feels more natural, but that means +4SPL just for an extra 2.4m of pool length

but then I thought if there are no lane ropes and no marking on the bottom of the pool to follow then 1.5SPL extra per length might be normal?

I don't have an answer although logic tells me you are on to something. I find it more comforting to swim with lane lines. Swimming in a pool with no bottom markings and ropes is disconcerting to me.

It could be related to the ratio of the length of the pool to the distance of your push off from the wall.
