insane shipping padding times 2 weeks on FBM orders killing sales?

Is anyone else having this same issue. If i do manual shipping templates, or amazon automation SSA it still shows these times. It has been this way for a month and has not cleared. MY OTDR is 98%, and my packages on average arrive in 3-5 days. This is so annoying, is amazon trying to eliminate FBM from the platform. I checked the package statistics and by my calculations, 98% of orders arrive in like 1 week, so it seems the way they calculate padding is very incorrect. Amazon is not dumb, so i believe it as an intentional technique to eliminate FBM, but obviously if they did it outright it would spark anti trust violations.
