Introducing Neil's Rule of .6

When dealing with small winning percentages in lopsided matches one needs at least 1 decimal pt for the small ME.
My formula gives 2.44% (KAZ XG2 says 2.45%)
So the formula is 2.45/(2.45+33).
I'll leave it to you do the math and see that now the TP is over 7%.
I know many mental math tricks to get approximations. When dealing with a difference in lopsided ratios like this and increasing the small figure by a smallish ammount..(ie 22%) you can just about increase the previous result by the same ammount..ie increase 5.71% by 22% and instantly you see it is over 7%.
Re: formulas...I've tried to work out something for 2 away scores, but haven't been happy with it. One of these days..I'll work harder on it.
