71% life remaining with only 100gb nand written (z400s 256gb)

Hi!

I have the SSD (z400s 256gb) about 1 year with Windows 10 in it.

Before firmware upgrade, the life indicator was 99%, after firmware upgrade and system “shutdown” and “start”, the life indicator was 71%. The SMART others numbers were not changed in the firmware after upgrade, onlye life indicator and (media wearout). I know that the media wearout is used to measure the life span.

MY SMART:
