Some fwiw comments:

1. Youtube videos by joe public have become like Wikipedia was when it first appeared, that is to say accepted verbatim as the 100% truth on a subject whether it actually is or not. More often, not. General statement, no idea about these two.

2. A common "mistake" in game modding is to use weapon, equipment, whatever performance specs that are published "lab" specs vs what was their actual useful performance specs in the field (much harder if not impossible to find), which tend to be very different and to a lesser degree of effectiveness.

3. Last but not least, various depth charge settings including depth are easily adjusted in the three depth charges files in the library folder.
Depth was changed very early on by various modders as iirc they never exploded below 150 so all one had to do was go below that for complete safety.
