Catra knives edge retention testing, M390 and S30V. How does our testing compare to Catra?

Catra knives edge retention testing, M390 from Lionsteel, Kershaw, Spyderco and the S30V Spyderco. How did this Shuffler, Dividend and PM2'S do? Thank you to Project Action for making the Catra testing possible and for sending the knives to me to test. As you'll see in the results our cardboard testing nets results in line with Catra and is just as scientific as thier testing is. I welcome any discussion about this and how the two compare. Also forgot to mention BJ as one of the guys testing, I added their channels down below with links.
