A few points:
Use of the word "track" above is going to be very confusing. In OSM,
"track" is a particular type of way that cars can more or less drive
on. You might use "route", if that seems reasonable, and if it
doesn't, you might explain what you really mean.
The normal best approach is fix OSM to have the right data and then
use it. (If you are picking intermediate points, that's ok.)
estimating times is tricky. It is certainly possible to be off. For
walking, you might see what the length is and how routing.xml
calculates time. Walking on level smooth ground is probably 2x the
speed, at least of hiking in hilly terrain on uneven ground. Perhaps
you could post the length and the time calculated, vs actual.
(you said "truthful", and I think you mean "accurate". truthful has a
notion of intent to deceive or not, vs an estimate made in good faith
in an overall situation which is more complicated than the data or
code accounts for. I realize the subtleties of English are not
easy, even for native speakers!)
