top pay 4 year mark full-time driver

I was a part one driver from October 2019 to January 2020. Then became full time driver in February 2020. When will I become a top pay driver?

I'm coming up on my 4 year mark... Can someone please tell me what Top Pay is. I've looked in the new contract & can't seem to find it. I can see that you get top pay at 4 years, but it doesn't say what the amount is.
