At 130' decompression will certainly be a factor using modern computers and by dive 3 it can be a huge issue.
I've dove quite a few computers side by side at those depths and deco obligation can be different by a factor of 10 so gas and time management are a bit more complicated than AOW teaches.
Certainly not rocket science but far beyond most divers desire or ability to deal with.Most of the non-professionals I dive with want to jump in,swim around and look at cool stuff and head back whenever they want or when they reach their personal turn point.Not deal with much planning, deco gas or stops other that a cursory safety stop.
