Right. Which makes best glide and Vy analogous and best loiter and Vx


Depends on what you are flying. in the Deb Vy is a tad slower than
best glide which gives 500 to 600 fpm while Vx which is a lot slower
gives the express elevator down at about 800 fpm or a tad more.
Gliding at Vx gives me a very fast and steep descent for short field
landings and a bunch of power. In the Deb Vx is definitely not going
to keep you up there longer. Maximum range under power is about the
same as Vy.

analogous.
