I agree with you Rebeckah ... Gail Howard - Advantage Plus is a real major piece of the foundation of the lottery software building
Its charts and their ease of use are readily recognized.
Re the "O" chart I haven't been there in a long while so after reading your post I checked it on the puter and in the manual and a weird thing is my manual doesn't list it
My Contents goes from Menu Option N - Lotto Astroscope to next is Menu Option V - Lottery Advantaqe Scoreboard.
I'll have to check out the O option more
