Default Debunking Glider Spoiler Turns Causing Spin Thinking

How come nobody ever states that these G loading increases are for level
flight? Since the glider is always descending, wouldn't it be better to
include something about the descent rate being maintained? What about a
climbing turn? Maybe some trig including the flight path angle?

Curious minds... And it's a slow morning before going to tow at the
Moriarty encampment.

I think you'll find that's more like 58 knots.

In a 45 degree turn, the G loading is 41% higher, but it only takes 20% more speed to produce that G loading, not 41% more speed.

You're right.
G-loading would be 1.41G in a 45 degree bank but the stall speed would increase by 1.19 so that would make it 58 knots (107km/h).
