This is the most extreme and insane set I've ever heard of

The heaviest EADG set I've ever seen has 75 and 55 for D and G, that's roughly 65 pounds tension on each and considered extra heavy. I'm surprised his strings haven't broken. Also the tension imbalance on the neck is huge with 89.1 pounds more tension on the high side of the neck than the low, this may twist or damage the neck. If he cares about his bass he needs to balance out the tension.
G 65 91.6 pounds tension
D 85 86.2
A 85 48.4
E 105 40.3
I recommend he study the tension charts here:
