When testing my new engine versions against older versions I use the nice
WhoIsBetter tool to determine weather or not the new version is likely to be

But I would also like to know how much stronger. Just an estimation would be
nice, just as an reward for the work. Putting the engine on FICS takes to long,
so I wonder are there any rules of thumb that I can apply?

New engine scores 3 to 2?
New engine scores 2 to 1?
New engine scores 3 to 1?
