I mean, it makes sense since the bail bondsmen have business licenses and likely some form of insurance and credentialing with the courts to cover the differences. All the court really cares about is if someone is liable/responsible/trustworthy.

I guess it's a question if whether you miss bail of the bail bondsmen can recover 100% of the bail despite having only lost 30% of it. I bet I can guess which it is.

Would the bondsman only lose 30%? From this discussion, they only have to post 30%, but the other 70% could become due when the terms of release are not met.

That's still a better deal for the bondsman, but it's also reasonable. If you don't show up for court, it doesn't seem likely that you'll show up to deposit the other 70%... But if you don't show up for court, the bondsman probably hasn't left, and they will be available to pay the rest of the bail amount.
