Line Length Deformation

Hello,

My Air-G Emilie 18 sqm has ~110 flights since 7 months and no water landing. Most of the manoeuvres are done on right side. In addition, this is the glider i've learnt infinity and it has many good and bad rhythmic sat tries on right side and 140 tumblings.

I've compared the A and B lines on left and right risers. All of the lines(especially A1, A2) on right side were a few millimetres longer than the lines on left side.

What should be done in this kind of situation?

Thanks.
