Time points

[izjwv30s]

So you'd like to attach a time at position 100 and 100, then select position 100 to 110 and execute Complete/Time... and the time delta between 100 and 110 is evenly distributed between 101 and 109?

not quite.
The distribution between 100 and 110 should ideally reflect constant speed over this section, based on the distance between the adjacent points.

i.e. Time(@ point n) = time (@ point 100) +
(distance (n)-distance(100)) / average speed from point (n) to point (100) )

what do you think?
