Help understanding gems please

According to these stat weights why does it never recommend for me to use the epic kraken agility gem? I have gems set to epic and have never seen it recommend main stat gem since BFA.

( Pawn: v1: " - Beast Mastery": Class=Hunter, Spec=BeastMastery, Agility=1.79, Avoidance=0.03, CritRating=1.38, HasteRating=1.37, Indestructible=0.01, Leech=0.01, MasteryRating=1.47, MaxDamage=0.91, MinDamage=0.91, MovementSpeed=0.02, Versatility=1.21 )

If you post your addon export string we can take a closer look at your case to tell you why it is doing what it is doing.

In general: the stat weights are just a rough ballpark – we don’t actually use them for optimizing. We use a much more thorough stat ranking technique that can deal with the interactions between stats and the rest of the special effects on your gear. We found out many years ago that stat weights just weren’t giving people the quality of result that they wanted.
