I think I found 2 bugs in the spreadsheet:
1st: The values of the serpent sting effect on the Shot Rotation tab are too low. The problem is in the Calculations tab cell H163. It doesn’t take into account any talents. That’s only a display bug however the calculations for the damage done with chimera shot are fine.
2nd: The calculations for the pet talent rabid are most definitely wrong. The spreadsheet says that the pet should have 5 stacks of rabid 87% of the time. I looked through the logs of our last week raiding and a lot of times it doesn’t even reach 5 stacks before it runs out. And it’s not only my pet. It’s the same for all the hunters I looked up on WoL

So, I did a quick rabid test today. Here is the combat log:
World of Logs - Real Time Raid Analysis
I went to the hero dummy with my pet, disabled all attacks but rabid, and let it attack for some time. Here are the numbers:
Pet attack speed: 1.54
# of rabid cast: 45
# of rabid procs: 166
So, my napkin math is that my pet was 900 sec under the rabid buff. In 900 sec it cast 585 melee attacks. And 166 procs out off 585 casts is a chance of 28.38%. I knew that’s to low because WoL don’t count procs that only refresh a 5 stacks buff but out of 45 rabid cast my pet only gets to 5 stacks 16 times.

I did another very short test and this time with bite active:
World of Logs - Real Time Raid Analysis
I used the lvl 60 dummy so my pet gets enough focus from GftT. The results are very similar to the test above. Even so my pet attacked more than 2 times as fast as before it only get to 5 stacks of rabid 5 out of 12 times. So it seems like bite does not affect the proc chance of rabid.
Pet attack speed: 1.54
# of rabid cast: 12
# of rabid procs: 43
Napkin math tells me that the rabid buff last 240 sec. That’s time for 156 melee attacks. 43 procs out of 156 melee attacks is 27.56%.
If I had to guess I would say rabid only procs from melee attacks with a proc chance of 30%
