After some debugging (related to issue in saving data) here are the results.

Fig 1 is the control test (likely Arylamide). It does not match that well with previous measurements...

Fig 2 is all newly tested hydrogel.

There is clear issue with ktk693, likely due to slipping of hydrogel during the measurement.

Maybe also issue with ktk697 (large error bar in birefringence).
