I know, the "if" is there for a reason ;) Also even homogenous distribution on a halve sphere  makes delays position-dependent, and I really do not want to calculate that.

"very few cables" - I really like this choice of words.
Also increasing delay: cables between nodes tend not to be great circle sections and therefore longer than my estimate.
