GWX3.0 - Enemy visual detection ranges

[banryu79]

Hello fellow kaleuns!
I was reading the "Patrol Guidelines" postend in the "Wolfes At War" site and considering to use as my personal guidelines in my games as they look to me very well thought out and potentially useful.

In the section about the uboat aspect presentend to the enemy ship and how this affect enemy visual detection range in different daylight conditions I red this passage:

For BOW ON and clear day with:
0 mps a ESCORT might detect you at around 4500
10 mps a ESCORT might detect you at around 3300

For BOW OFF (i.e. Side On) and clear day with:
0 mps a ESCORT might detect you at around 7400
10 mps a ESCORT might detect you at around 6000


For BOW ON and a clear night with:
0 mps a ESCORT might detect you at around 1200
10 mps a ESCORT might NOT detected you <-- NOTE!


For BOW OFF (i.e. Side On) and a clear night with:
0 mps a ESCORT might detect you at around 2800
10 mps a ESCORT might detect you at around 2000


Note that these are for ESCORTS, merchant ships are in comparison blind.

I do not undestand what the "mps" acronym (at least I think it is an acronym) stand for? Somebody who knows it can help me? I have the impression it could refer about sea condition, mybe wind speed, as it seems logical this aspect factor in visual conditions...

Also, and this is a question for the experienced kaleuns here, would you confirm or deny these values, based on you personal experience (with GWX or NYGM as a context)?

I am really intrested in knowing about these matters!
