Brake Improvements - Looking for thoughts

Well, I got the new master installed and plumbed. Have now bled these things about 5 times, and still have a squishy pedal for the first half.

Hooked up my power bleeder pumped it to 10 psi, opened a bleeder and nothing came out. Pushed the pedal a little and the master sprayed fluid everywhere from the reservoir cap. Not sure why the fluid went up and not down with an open bleeder.

I guess I'll bench bleed the master again amd start over. I get no bubbles from any of the calipers and have pushed just over 2 quarts through the system.
