WitP Editor Devices Values

[exltcmts2]

I have lost an old crib sheet on the appropriate values for mines in the Devices category.
Mines Penetration 0=ship-laid, 1=sub-laid 3=air-laid
But what does the value in Accuracy mean: Is there a value for contact, magnetic, acoustic, etc.?
The Japanese only ever had the Type 88 special sub-laid mine and only the KRS could lay them. Except for about 250 mines captured at Singapore, the IJN never had a tube-launched mine. The best way to handle this is limit the size of pool for Type 88 mines and turn off production.
Thanks
