I seem to build up moisture in my clutch fluid very rapidly and wanted to see if anyone had ideas.

I went to the track last October and tested for moisture content afterwards. It was 4% which was weird because I changed it a year before.

Anyway, I bled the system and tested it after a drive. It was at 0%. Here we are 5 months later (with very little driving) and it's reading 1% already.

Is this normal on these cars? My daily driver is 5+ years on the original fluid and still reads at 0%.
