lashing distance for high mod lifelines

[seawolf]

Hello all,
Is there a standard distance between the lashing thimble on the end of the line and the lashing point that is good to use when lashing amsteel, or other hi mod line to ensure enough room for take up and creep, and not to much for a lashing to be to long and unattractive.
It would make final line measurement easier if there is a proven absolute or formula depending on length and diameter of the line.
Thanks and fair winds.
