Using all elsets to predict an observation near the time of epoch, and ELCOR
+Vec2TLE to adjust the last set, I get residuals below .08 degrees with:

STARSHINE Elcor
1 25769U 99030B   99157.23801395  .00032449  00000-0  39389-3 0    80
2 25769  51.5933 252.8656 0012697 193.5637 166.5016 15.59826494  1537

except for elset issue 1 (0.15) and issue 2 (2.08)
