Expertise Chart?

does anyone know where i can get a good chart that breaks expertise effectiveness by level?

I had one but the website is gone and I cant seem to find another good one. My main thing is..im wanting to see what the differences are between levels 9 and 13. Man i knew i shoulda copied that chart to my harddrive

The difference is 1 E for 5E skills.

It's not so hard to memorize. It's basically 5 and 10 E skills that matter most, since you'll use those more frequently, the 15E break at almost every level and the 25E skills at every level (4% = 1/25).

For the 5E skills main breakpoints are at 8 and 13, for 10E skills at 9, 12 and 14.
