Take your time, make sure it won't resist the bend, otherwise your bends will be fugly. My first set was all kinds of ugly, my redo a couple of months ago was so much better.
It it takes 40 minutes though, you might try a higher temp on your heatgun.
Took me forever to edit this, but I took a look at your previous post with the pic you took. That picture looks fine. When you bend any material under either heat or stress, the corner will deform a little. You get that slight flatness at the back of the bend, but as long as you don't have bulges at the sides or folds on the inner radius, it is a good bend. Keep doing what you are doing, and seeing the water you use to lubricate the insert boiling is a good indication you are getting close to bending time.
And yeah, I started with acrylic too. Apparently PETG is easier, shame on us, eh?
