If you have diagnostic cyberware (such as a visual overlay), I think if you go a certain amount over PDS quickly (such as with @holdback or similar reasoning) it should give you a warning that you are at PDS risk. Maybe big flashing yellow warning or similar.
This was a niche case (probably) but I think it would be safe to say that if you jacked your body full of enough chrome to hit a high PDS limit, or do other things that cause it, that SK would have some kind of warning that triggers when you are too far gone for liability reasons. Maybe you can disable it with a cybertech.
Anyways, open for discussion.
