Tim,
Congratulations!
Convergence is a tricky business, as I am sure Pete can tell you. You may know this, but you will find the static and dynamic convergence portions of the procedure tent to be iterative. Once you have done static then dynamic convergence, go back and re-tweak static and then dynamic convergence. You may iterate to a better solution. I assume you have degaussed the set? If not, this may also help with purity and convergence.
The HV performance on the CT100 is always a bit disappointing. When it "blooms" and gets a dark screen with a fuzzy blob, it is an indication your HV supply is overloaded. Reduce the brightness and contrast to a lower level. The tendency is to turn up the brightness and contrast for a good picture, and then when a scene comes with lots of white content, the HV supply cannot meet the demand and the HV and focus drop out of regulation. I do not suspect there is anything wrong with the set, just the irresistible temptation to turn it up a bit too much.
