Their GAA is very close over those 2 years. SV% is not. You haven't demonstrated how Markstrom is any better over that tineframe.
Do you think the Pens are some defensive juggernaut?
Markstrom is better based on GSAx but it's not by a ton. In the 4 years Markstrom was on Calgary:
-2023-2024: +2.6 GSAx for Jarry, +13.7 GSAx for Markstrom
-2022-2023: -2.8 GSAx for Jarry, -3.1 GSAx for Marksrom
-2021-2022: +12.8 GSAx for Jarry, +10.8 GSAx for Markstrom
-2020-2021: -11.8 GSAx for Jarry, -9.3 GSAx for Markstrom
Total: +0.8 GSAx for Jarry, +12.1 GSAx for Markstrom
2020-2023 were basically equal for the two, while Markstrom was notably better than Jarry in 2023-2024. Still though, the idea that Markstrom brings back a 1st while Jarry is a negative value cap dump is just idiocy.
The reality is that Markstrom cashed out on a good year, hence why he brought back a 1st, but Jarry is coming off a mid year and will likely get a very mid-like return. Something like a "2nd but take back Husso" type of return.
