how modify tasklist's cpu cpu % usage?

i'm perplexing tasklist out slight radical some-more x percent cpu (to after kill taskkill.)

how i know percent format represents?

the documentations says:

tasklist options

/fi   filter               

and filter competence be:

cputime         eq, ne, gt, lt, ge, le        cpu format: hh:mm:ss.
                                              hh - array hours,
                                              mm - minutes, ss - seconds

if i try

tasklist /fi "cputime gt 00:00:10" 

it works.

but i

tasklist /fi "cputime gt 90"

it doesn't.

how i know format paint 90%? 80%? what's charge between cpu use cpu use percent?
