Can this quarter go any mellower without losing the stall?

I set this up and it stalls properly at the top. I am referring to the underside of the board stalling like on any rock tricks. I want to know if I can go any mellower with the radius and not lose the stall. I tried a 72" radius with the same height and it no longer stalled at the top. So it's a pretty narrow range I'm working with. I don't know if there's some kind of height/radius ratio at which when you go past it, the stall goes away from being too mellow. Thanks

Wheel size, truck height and riser thickness will be a factor to take account of.

You could maybe go with a 6-foot radius but much more mellow than that on a ramp under 2 feet would probably not allow you to lock in trucks unless you are skating 48mm wheels :(

I have smaller wheels. So when you said 6 ft, can you just tell by experience or is there some way to know a height/radius ratio that wont work? For instance, that site has plans for 3 ft mini that uses 6 ft radius. So the ratio is 2. But the quarter on the site has height of 2 and radius of 66” and that ratio is 2.75. The 6 ft radius your suggesting would be ratio of 3 at the same height. So is that the ratio not to go past in ramp building?
