Ok, I'd change it so that instead of forcing either half or full fill, we 
chose the fill type based on the percentage.

0-15 = Off, 15-70 = Half Fill, 70+ = Full Fill

I've picked the figures at random and they will probably need adjusting.

I'm not sure what the "AutoDetect (Default Half)" is for? Probably wouldn't be 
needed if the above scheme is used?
