Here is a spreadsheet I made during 1.1.0:
https://docs.google.com/spreadsheets/d/16e6P2A-facXTTO_DHyiZu6KOlDC2YOnlF2W2VDlKZow/edit?usp=sharing
I have retested all of the damages at all of the same (specific) scenarios and they are the same in 1.2.0.
I took screenshots of all throws at 100% in 1.1.0 in training mode, and then I tested all of the throws again in 1.2.0, and the enemy (with no DI) is sent to the exact same training mode squares when hitstun ends. Rod's angles are unchanged.
I tested Rod's kill percentages standing at the
same position of FD in both versions.
Methodology: Go into training mode, select FD, select Isabelle as P1 and Mario as P2, increase number of CPUs to 2, change speed to "1 Frame" (so there is no movement when using Side B), reset, smash-throw Rod at the CPU on the left, and see when it kills. (The CPU is set to "Stop". Make sure each throw does consistent damage in all trials.)
Rod FThrow (15.3%) 146%
Rod BThrow (12.3%) 292%
Rod UThrow (13.3%) 143%
Rod DThrow (2.3, 9.8; 12.2%) 278%
They are the same in both versions. Rod's knockback is unchanged.
