Is there a known pool of NBW starting stats?

Title says it all. I'm considering taking data to figure out if there is a regular range of stats that NBWs have. I wanted to post here first though to make sure that this is something that actually needs researching. If this is already common knowledge, please let me know ^^ i searched the wiki & grouse guides and did not find an answer.

NBWs mostly range in the low to mid 200's, some are around 180-190 but I've never seen one at or above 300.
