You fell into the 'precision' trap of converting a number to +/- 5 m into
something +/- 1/10,000 of a foot! Only a difference of 6 parts in a million!
180 - 200 ft is close enough, allowing for the bow in a tape measure at 45
- 55 kt.
200 ft is 3 - 4 wingspans depending on your glider. 200 ft is actually
something I remember as a good guideline from early gliding days in the UK
more than 35 years ago as well as when I moved here and read the GFA rules
- and still good advice (= sound airmanship). You can't go far wrong if
you treat consideration for other people as being an indicator of good
airmanship.

Think about this for ref 55m is the min requirement for areo tow (conversion

I've known its 200ft since forever, I guess I had good instructors, but--
What does 200ft look like glider to glider in the air?
Pretty hard to judge and I do not measure off the feet visually when I'm
flying, it becomes a TLAR judgement.
