I emailed George for Flight School and we agreed that I needed Stroke 911 first.
I worked on the three aspects of my stroke last night, focusing on the dart speed, dart parabola and side to side path of dart, one at a time, for fifteen minutes each. I stopped analysing other factors such as where I stood at the oche, my stance and my grip, etc.
It was zen-like, whatever that means. I was able to find my 'comfort' speed and stroke (without being conscious about the mechanics) and the darts landed more consistently on the board. I don't want to get ahead of myself and say it's going to be fine the rest of the way. But I knew there was progress made.
I'm planning to give the same exercise a go for the next few days (or weeks) and see what happens. Hopefully I'll be able to keep a consistent stroke.
Thanks, master yoda-George.
