[REL] German torpedo fix for UBM stock

[RFB Team]

After seeing the thread on excessive German duds, we took a look at the file for the German torpedoes thinking the issue was caused by one of the chance parameters being 1.

While this was true, this was not the major source of the excessive duds.

The problem was the angles were mixed up so the following percentages for duds were in the file for most of the German torpedoes. Keep in mind that a 0 angle in this file is a perfectly perpendicular hit. The angle given is the angle of deviation from a "perfect" shot. We conducted experiments when working on the US torpedoes to confirm this. Here is the order the angles were listed in, with the associated dud chance.

Angle: 50 to 90
chance= 1

Angle: 21 to 50
chance= 5, 33, or 50 (depends on torpedo type and date)

Angle: 0 to 21
Chance= 100

Since the known problem with the German torpedoes was the whiskers on the the detonator not working correctly with wider angles, their reliability was known to drop off after an angle of 20 degrees. This means the dud chances in the stock file were reversed.

So the angles are now listed as

Angle: 0 to 21
Chance= 1.1

Angle: 21 to 50
chance= 5.1, 33.1 or 50.1

Angle: 50 to 90
chance =99.9

Because of the issue with 1 being read sometimes as 100, we've taken the conservative approach and added or subtracted 0.1 to any "Chance=" entry in the torpedo file using a whole number. This was done for all gyro, depth keeping, and premature chances.

In the process of making those changes, the other settings were also checked for errors.

This is JSGME ready
Edit: this is a fix for stock, and as such, will not have the RFB team's usual nitty gritty treatment.

Will this be incorporated into RFB's next release, too?

The RFB file will include some realism enhancements. An even more detailed version will be issued with a later RFB release as we'll neeed to do a lot more research.

What file is this located in?

It's so typical me, not to speak up on some issues for some strange reason sometimes. Or just not paying attention to some discussions. I messed with this last summer, but made other settings. Which seemed to work quite fine:

Angle: 0 to 15
Chance= 5.0 (higher than RFB - giving a slight chance of a dud)

Angle: 15 to 45
chance= 33.3 (like as in 1/3)

Angle: 45 to 90
chance =85.0 (lower than RFB - giving a slight chance of a hit)

For Type I, 1938-31/7-1943
