and regarding the question of "standing" against "hanging on the nails"...
Also in roman style it was not hanging on two nails in the wrist (or even hands!).
Feet were also nailed to support the body weight. Sometimes even a "sedulum" was used.
There is archaeological evidence of feet nailed at the side of the vertical beam, as in the picture, but in many christian depictions a pedestal is shown.
Considering that at the time of early christian depictions, romans were still crucifying...
well, maybe the big difference is that the romans were leaving the condemned on the cross for hours and even days and not for a quarter of an hour!
Feet nailed in the philipine way, they are standing on a horizontal platform, no weight on the nails.
Uncomfortable, and it will cause pain, but not in the same league as taking your full weight hanging/pushing on the nails.
In roman crux they hang on the nails in their wrists. or push down to take the weight through the nails in their feet/ankle whatever.
The feet are suspended by the nails for the most part(even with a slanted footrest.-> hanging on the nails.
OFC I wouldn't recommend crucifiying someone in the roman way,
I only wanted to point out the real difference between a make believe crucifixion as done on the philipines and the original real crucifixions in antiquity.
For me the philipine crux is a short, very symbolic.
Drawings, 3D renders and photomanips can give a more realistic and indeed better depiction of what a crucifixion was back then.
To each their own of course, but real suffering? to me it is not.
