Pretty sure Ray Lynskey had a 30kt vario in his glider. Not to know how fast he was going up, but how fast he was coming down in the wave

I'm trying to think what you could do with this information that would be useful to you.

It's not like a reading between -10 and -30 will make you fly faster than simply knowing it's pegged at -10. You'll already be flying as fast as you dare!

You're also probably not going to think to yourself "Oh good, I got out of that region of -25 and it's only -15 here ... I'll just circle here for a bit..."
