Pyrite Infuser appears in the calculations twice - it looks like the one in P131 is just misnamed and should be Tears of Bitter Anguish. The result for it should read as average haste, not AP, as well. It looks like this is just a name mixup and the actual data processing is fine.

I would like to suggest having a standard color for fields that are meant to be edited by the end user, for the sake of usability. For someone who has not been using the sheet for awhile (not me!) it is not always easy to determine which fields are meant to be edited, especially when it is only one or two in some tabs. Right now it is light yellow in most fields but pale blue in a few others (mostly hand adjusted stats, not user selected settings) - but pale yellow is still used as the background for some cells that are not meant to be edited, such as on the gear tab. Perhaps I'm just being picky, but it seems to me that sticking with one color makes it more obvious what you're supposed to be adjusting.

Simple. When there is a chance of iAotH to proc of 10%, then what happens, when iAotH is active? You get a bonus of 15% haste with 5 points and 3% with 1 point. So, during the uptime of iAotH you fire more shots, which each has the 10% chance to proc. So the haste effect of iAotH has to take effect on the uptime, the more points you put into this talent, the more chances to proc because of the bigger effect of haste. And what bothers me, is that the more haste you've got through gear, the less the uptime of iAotH is calculated. Maybe it is right, but it seems unnatural. The more shots you fire, which each a chance to proc, the less is the uptime? Sounds wrong to me.

I've done some extensive testing on PTR to get data about how focused aim interacts with the new expertise for pets thing. It's clearly bugged, but the way it's bugged is pretty strange and I have a feeling it won't be fixed before live so it'll probably need to be reflected in the spreadsheet (I've been bugging it for awhile). I haven't quite figured out the pattern though. Here's my testing results:

1 focused aim:
7% hit - .6% dodge
6% hit - .9% - 1% dodge
5% hit - 1.9% dodge

2 focused aim:
7% hit - no dodge
6% hit - .8% dodge
5% hit - 2% dodge

3 focused aim:
7% hit - no dodge
6% hit - .4% dodge
5% hit - 1.2% dodge

Under normal circumstances 1% hit seems to be about .8% dodge (which is logical since 6.5% dodge is the total with no expertise) so these results are pretty weird. Focused aim has some effect but not the expected effect.

I also tested the draenei hit buff and it seems to have no effect on pet expertise.

I maybe a thiko here, but how do you enable dragons eyes in the settings tab.

Cheers in advance
