Topic: question on bridges

Is it weird that I get my best bridges so far (on bridge torture test.stl)  when it's bridging at 15mm/s ??

Everything I've heard says that faster is better for bridges, at least 60mm/s +. But when I use fast speed for bridging, it doesn't anchor the bridge strands in good enough and they snap off near the perimeters of where they are anchored to.

My SD3:  Clear plexiglass case, case heater, X axis stabilizer, Z axis stabilizer, thumb screws, filament guide, heatsinks on all motors, extruder fan, controller fan, heatsinks on motherboard, Y rod pillow block, USB and Power on/off switch, fully calibrated including trimpot tuning. Am I missing anything?

55mm/s it won't anchor. maybe 200C for temp is not enough
