Hi I'm a user of Enterprise reCaptcha and considering lowering(?) the level of ChallengeSecurityPreference from "Balance" to "Usability".

I can not find any detail especially related to

1. How you determine which traffic is risky per each enum value; as this is not from the score-based reCaptcha and also want to understand what is the difference, too. (Such as v1 uses this many factors but v2, score-based uses this many factors....)
2. How much increase of risk we have to expect with this change (more chance of bot attack?)

And want to know if anyone from reCaptcha team can help with it.

Thanks in advance.
