d3d_lodfactor interfere with clip0 and clip1

I read in the manual , clip0 and clip1 works with percentages of view distance , okay cool It works as stated .

lodfactor also states in manual it works in percentage of viewdistance , no problem it works.

but , whenever I use clip0 or clip1 , plus , use lodfactor , the clipping distance suddenly shortens ??

I dont get it , am I missing something .

entities can be clipped at the distances set by lodfactor and clip_far, and determined for each entity by clip0 and clip1 where it happens, after 1st 2nd 3rd lod or only at clip_far.
