1. It's a little early for Senate predictions

I don't know how you can claim to know how they will trend two years out, particularly since we don't even know who the opposition nominees will be.

2. The vulnerable US Senate seats up for re-election in 2022 are going to be.

Vulnerable Democratic
AZ(Kelly-D) if Ducey-R is the GOP Nominee.
NV(Cortez Masto-D) if Sandoval-R is the GOP Nominee.
NH(Hassan-D) if Sununu-R is the GOP Nominee.
AZ,NV,and NH are battleground states with Current or Former Governors as the GOP challengers.
Democrats are safe in CA(whoever Newsom appoints-D),CO(Bennet-D),CT(Blumenthal-D),HI(Schatz-D),IL(Duckworth-D),MD(Van Hollen-D),NY(Schumer-D),OR(Wyden-D),VT(Leahy-D),and WA(Murray-D).
These are strong Democratic states.
Vulnerable Republican
PA(OPEN Toomey-R)
NC(OPEN Burr-R)
WI(Johnson-R)
FL(Rubio-R)
OH(Portman-R)
IA(if OPEN Grassley-R/Vilsack-D is the Democratic Nominee.)
PA,NC,WI,FL,OH,and IA are battleground states with top tier Democratic challengers.
The GA US Senate seat(Loeffler-R vs Warnock-D).

3. You have OH going Democrat

which is highly unlikely, to say the least. Iowa is no longer a battleground state, nor is Florida. And Burr will likely have his seat back if he wants it. I think we can classify your list as wishful thinking.
