ok first off, i really do agree with low rates for learners, just not stupid low, whichhhhhhhh is what this litle story tells us.
our club chair woman is flying a members Limbo dancer, learning on it, she flys a little close to the pits and we all start shouting over in jest "no flying over the pits" and other things along the same line, inculding my " no flying " then it dives and dosnt pull out... weird, it had oodles off room, and my line was only a joke

Turns out they wernt using a buddy box, and the rates had been set way low. so, she lost concentration when she turned round to us lot and the plane started its dive, when the guy took his plane back he didnt have enough rate to pull the plane out of a 20 ish degree dive in 3-5 seconds. thats LOW!!!!!!! espicialy for a Limbo.
for me i wouldnt consider rates as low as that as the pliot flying the plane. + it also sets up bad habbits of over control in later planes on higher rates.
