This calc which is based on the original
As far as I can tell the general methodology is correct, but the problem comes here in this part:
Model both real and portrayed lightning bolts as cylindrical channels of current.
More specifically, the part where the apparent diameter of the fictional lightning bolt is used as means to infer the width of the channel the current passes through.
This is an incorrect thing to do, as the apparent size of a lightning bolt in real life is much larger than that of its channel, which is only the width of an human thumb. So the apparent size of the lightning bolt during both feats cannot be utilized to find the width of the channel, you can only do so if the width is stated like it is in real life, which is how the orignal calcer from Narutoforums got current density/m2 (955e+6 A/m^2.) for real ligthning in the first place, if one were to apply the same methodology for real lightning and infer the width of the channel based on their apparent diameter they would get ridiculous unrealistic results.
I brought this up earlier in another thread and DMUA suggested that we could instead use secondary evidence to confirm whether the width of the channel is actually that of the apparent size of the bolt, such as using the bits of melted ground here, it seems fine at a glance but more input is definitely needed.
However even if that's accepted the general method relies entirely on the apparent size of the bolt to infer the width of the channel so it's not very reliable as it is.
