ok thanx
so evidently we are talking more like 10km than 5km of straight
border there
which will be much harder to surpass even on plru

& i have to wonder then if it doesnt just boil down to a question of
whether 3 or more monuments in a row can ever be considered
perfectly straight
when we know they must always deflect off of one another by at
least a few mils of a second of arc
just owing to limitations of survey accuracy

but since caus & egly were specifically mentioned as straight
i think any series of practically straight monuments would qualify

& this would make plru look pretty good in places i think

but it is jespers question
& his to decide which chains of practically straight monuments
are acceptably sober
& which too tipsy to qualify

secondly
this single clean cut of the curonian neck & beyond
which i think you are indicating
also produces an appreciably large straight fraction of all ltru
suggesting kevins interpretation was correct

in that event
i cant help suggesting penon de velez de la gomera
with its perfect single cut neck as entire border
even tho i distinctly recall the question was only about europe
if indeed it was the question
