It might just be your MityVac is faulty and not able to hold a vacuum. I replaced the seals on mine and it is working good again.
Your bleed hoses also need to be tight on the brake bleeders. Do not loosen the the bleeders too much, you will suck air from around the brake bleeder threads. You can take the brake bleeders out and wrap ptfe tape round the threads to stop that happening during bleeding.
If you still cannot get a good pedal after all this with your Mityvac, then you will need to do the old 2 person brake bleed with someone locking the bleeder after every downstroke of the brake pedal.
Make sure the master brake level does not go down low.
The order of bleeding the brakes you have is correct.
