Strange, I have a lot more...
And much more can be done, but I can't tweak my solution without good tweaker.
I know, I'm a hoster of this level, but your solutions didn't help me to make more (except Peters solution which gaves me +3.1415 bonus)
offtopic: I have a clue (for basic AR1 level (50 basic levels)), how to tweak it and it's 100% possible, but needs additional ~1-8 hours of tweaking (depends on luck). If someones wants - I can share my concept. You can PM me for it.
