The nails contribute because they cause blood loss and potentially blood poisoning, but the basic cause of dea ...[text shortened]... repented of his sins. If cause of death was asphixiation then they wouldn't be able to do that.
Yes, I had meant to add that, yes, the Romans did not break his legs. This is what caused extreme pain when trying to breathe, since it was necessary to lift oneself up a little in order to breathe and it was almost impossible with broken legs. Naturally this didn't occur until the Romans came by and wanted to rush things along, this is why the three of them could still speak without a huge effort, their legs were not yet broken. I'm sure the test subjects' legs were not broken either, in addition to not actually being nailed to the cross, and they probably had a nice little built-in ledge to stand on.
As to the actual cause of Jesus' death, I'm sure it was not asphyxiation either (it probably helped things along with the typical crucifixion). As I said, God was merciful in any case and took him relatively quickly (and before His legs could be broken, fulfilling prophecy in Isaiah). Heart failure sounds as likely as anything.
I find the whole idea of "test subjects being subjected to the cross without
actually recreating what happened to Jesus" as just being more speculation, it doesn't prove or disprove anything, because they did not have the same experience as Jesus (obviously).
