^i thought physics was similar to maths, mr pig! :D
anyway, just to point out that i'm not being a smartass or anything bringing the whole 14.9% versus 17.5% thing up, I only realised that there was a difference recently- I think I recommended BK's to someone on HC, and I said they could take 17.5% off, and someone else corrected me! :oops:
:twisted:
