Ignore the cfg and sim files, it's the zon file that is important, and you must keep the following in mind:
- the values SH3Cmdr uses are not meant to be metre accurate. Indeed, do such
verified values exist? The values used are deliberate so that players don't simply go to uboat.net and take comfort knowing exactly how low they can go. Keep in mind, for example, that after sinking HMS Barham U-331 (VIIC) was reported to dive to 250m when the theoretical crush depth was rated around 220m. And for this reason, considering that by default SH3Cmdr decreases the depth, it defaults a bit deeper than the usual theoretical depths. And with SH3 taking damage into account as well, thus decreasing it even further, I think the overall result of my approach is quite plausible.
I guess what I am saying here is that there is more to this particular figure than just looking in a book and taking the quoted figure as gospel.
- the values used by GWX are intentionally modified from the values obtained through their research for much the same reason - to keep the average player on their toes, just like in RL. So, if you use theirs as your seed, then you will be modifying modified values.
- the values stored in the zon files are a hex representation of a decimal number. Thus you need to convert any decimal number to hex (ie, if you want a 200m crush depth, then you need to write 280 to the file). This is the biggest trap that modders fall into. SH3Cmdr does the conversion internally, so if you want to modify the values through SH3 options.cfg, just enter it in metres and SH3Cmdr will take care of the rest.
Hopefully this is enough to clarify it for everyone.
