I have heard that it gives ''optimistic'' numbers but it at least is a simple comparison tool.
Yup.

I've used it extensively to compare actual wattage draw versus power claims.... and glow and gas engine power output predictions versus observed.

IMHO it is about 20% too high in it's estimates for most cases.

However if you adjust for this, it is a very good tool.
