I am not sure how I missed adding http://www.ah-whoring.com/ to my blog list. Sarainy has compiled a great shreadsheet that does the math on all the common tricks for each profession. Like many people, I have several spreadsheets for different things. Not many are my own, but some that the comunity has provided.
What Sarainy has is a single spreadsheet to replace them all. I have thought about doing it, but was doing good enough with all of my specialty spreadsheets. I was not quick to replace them but this has been good as I move into other markets. With all those other professions so handy, it makes it easy to use it for my other things.
I now have http://www.ah-whoring.com/ in by blog list. It is a blog that I was already following, just never made to my list. So thanks Sarainy for your blog and I am sorry I didn't link to you sooner.
