Are UWSA 1/2 more predictive now?

Im about 18 days out from my exam and did UWSA 1 and 2 back-to-back to simulate the 8-hour exam. I'm not gonna lie, I found the first couple blocks of UWSA 1 pretty difficult and definitely thought I was blowing it. After the 2nd block I took a 10 min break, composed myself, and continued. I ended up with a 245 on UWSA1 and 249 on UWSA2. I've looked around and haven't really been able to find any solid info. Should I consider these scores to be overly inflated like they were in the past? I took nbme 15 on the 15th of this month and scored a 220. Any ideas?
