Ritchey Superlogic post - minimum insertion point

[ak47]

Can anyone who has the Superlogoic 1 bolt post tell me where's the minimum insertion point on it? I'm deciding between 300 and 400 mm size, but don't know if 300 will be safe to use.

The Min Insertion mark is 100mm from the end of the post on mine.

Thanks a lot. I guess I'll be safer with 400 mm and just cut it a little bit.
