1: The average damage of the Grizzly includes the extra damage from the smite attack (+15% ed) under the assumption that both attacks happen with a probability of 50%.
2: This is the average damage per second for all pets under the assumption that all attacks hit. The AR of the pets and the DR of the enemy will influence the correct DPS.
3: All pets wait 15 frames between each attack. This delay is included in the calculations of the damage per second (DPS).
4: The fire damage of Enchant is not calculated as this would need extensive knowledge about the skills and equipment of the character that casts it (synergies, mastery, rainbow facets,...).
If you want to include the damage from Enchant to the DPS, add (average Enchant-damage)*25/(attack-frames+15)*(number of pets) the the result for wolves, and (average Enchant damage)*25*(1/(attack-frames,normal+15)+1/(attack_frames,smite+15))/2 for the Grizzly.
