Be aware - Green-Up multiple times!

[Woolfold]

Just building my Rules and my major problem was stopping when I wanted to.
I found it was the Greening rule, which was set to fire once.
Firing twice still caused problem due to the speed I had set the other rules at.
Finally, after 10 or so races (not many, but enough to see success beginning to pop up!) I have found that 3 times is pretty good, so I green-up 3 times, 3 seconds apart.
Hope this helps someone!
