Linkedin Commercial Use Limit on Search

hi all...i was restricted by linkedin...they say i made too many searches and so until next month when i search i see only 4 results...i'm trying to test with several profile what is their real algorithm (obviosuly they don't declare anything)...they say:
"We don?t provide the maximum of number of searches that can be conducted. The limit is primarily based on the number of people searches that yield profile views. However, the overall number of profile views and people search page views are factored in as well.

Please know that members generally don?t hit the limit. For those who do hit the limit, they've used the full allotted number of people searches, or they've ran less than the allotted number of searches but viewed a disproportionately high number of profiles."

do you have any info about it? did you run any test?

UPDATE
few days ago google if you were logged with a linkedin profile was showing only the first 30 results..maybe was matching the new policy of linkeidn ...so 3 searches in linkedn per day should be ok...i will try and test if increasing brings problems

never hit this limit before, just a though, would it help spreading the load on several accounts? so instead of searching with 1 account a lot, search with 10, this way you'll be way under the limit.
