Odd Bot Pattern?

In looking at the stats for one of my sites, I am noticing a pattern in the number of hits from various hosts.

The total hits are always in multiples of 300.

Like 300 or 600 or 900 ....

For example:

ti111210a080-9341.bb.online.no300
pool-71-254-180-223.lsanca.fios.verizon.net 300
c-68-48-242-29.hsd1.va.comcast.net300pool-72-67-63-29.lsanca.fios.verizon.net 300
c-24-6-191-243.hsd1.ca.comcast.net300
120.80-203-102.nextgentel.com300

70.208.118.70.cfl.res.rr.com 600
c-67-184-234-224.hsd1.il.comcast.net 600
ip68-2-88-31.ph.ph.cox.net 600
adsl-68-78-108-50.dsl.emhril.ameritech.net 600
243.80-203-11.nextgentel.com 600

Etc.

This is quite suspicious as the number of hits for most hosts are all over the place. The multiples of 300 stand out.

Anyone have ideas about what is up with a pattern like this, where the hosts seem to differ?

Pfui

Beats me, sorry. Bot Spotters are trying to solve another "Who are those guys?" mystery (Part 1 [webmasterworld.com]; Part 2 [webmasterworld.com]), but this sounds completely new/different. Hmm. A few Qs, please?

-- Are the hits to .html files only? Or do they get graphics with .html? What about other file types like .txt, .mov, .ico, etc.?

-- Regardless of file type, are your 'multiples' visitors hitting the same files? Do they came back again, and do it again?

-- Are the User-agents different, from host to host, and/or from visit to visit?

-- Are the hits rapid-fire, akin to a robot, or is the rate more 'human'?

TIA for helping ease my curiosity, even if I can't ease yours!
