The Track by Track analysis has been done for 7p3GeV_fixedTarget_2020 file reconstructed with SL21d and SL23e.

The chains were different:

SL21d : "DbV20220117,P2020a,StiCA,FXT,BEmcChkStat,picoVtxFXT,PicoCovMtxWrite,-beamline3D,-OPr13,OPr40,evout,-hitfilt"

SL23e : "DbV20231004,P2020a,StiCA,FXT,-mtd,picoVtxFXT,PicoCovMtxWrite,BEmcChkStat,-OSpaceZ2,-OGridLeakFull,evout,-hitfilt"

The results can be found at

The differences are within ~0.1%.

My guess is that the hit distribution difference reported by Yue Xu (https://drupal.star.bnl.gov/STAR/system/files/Acceptanceindffproduc_20231208.pdf) on slides 6-7 is coming from her triton and He3 z-cut.
