Newbie help required!
Lets suppose I am on a shallow final glide, 60k out in my 40:1 ship,
cruising at 60 knots. Recent thermals have been at least 5 knots and I
am coming into some big lift. For the discussion rough air Vne is 100
knots.
What strength thermal should I take to increase finishing speed to Vne
and how much (if any) time will this save me?
How do I estimate this at the time? What is the latest point on track
to take such a thermal?


Need to know sink rate at Vne, right? Also, 40:1 is at 60 knots?

As a guidance:
If your MC-Value for final glide is lower than the thermal-strenght you
encouter, use the thermal up to the altitude that allows you to continue your
final glide with the NEW MC-value.

Example:
Final glide with MC=1.0 m/s
New Thermal 2m/s.
You gain 300 additional meters of altitude to continue now at MC=2.0m/s to you
destination.
