I've just completed leveling cooking and fishing from 1 to 300 using your guide at http://www.elsanglin.com/fishing_and_cooking_horde.html
The guide is great, however I consisitenly go way more fish per stage than the guide suggested. I believe it is because the rule of thumb about the number of caught fish per skill point is not accurate. For example from 290-300 I caught about 120 fish. From 290-298 it was about 9-10 fish per point and from 298-300 it was 13 fish and then 15 fish. This is just an example as it happened from about skill 150 on.
Not a huge deal but thought perhaps more experimentation is needed to determine the actual fish per level instead of the at http://www.elsanglin.com/role_of_skill.html
Thanks for the guides they are great. Now that I'm at 300 I guess I need to level a bit more. (This is on my druid who is only 44.)
