Hello Paul,
thanks for your advice, I actually have good hair in the back and sides.
Let me show you this picture of me.
Do you think 65% is still ok for me?
Or can I get away with 70%?

The pic with short hair was a few months ago when I cut my hair real short, now I am letting it grow out as you can see from the attached picture.
Hence why the pictures look different.

Regards
Japan
