I'm working inside a box, so im posting this as a sanity check.

Which radar performance model is preferable?

Performance model A:
A fixed max range on both the SJ and SJ-1, max range depending on the radar, with reliable contacts within that range.

Performance model B:
A variable max range depending on the aspect of the targeted ship.

This is the reason i post this, because i've been told that radar performance of this nature isn't quite correct. I attribute this to flaws in the game engine. But in my mind it seems more variable, dynamic, and therego a bit more realistic. But i degress, i could be smoking crack here. So, to understand what i'm talking about, here's the results of 3 or 4 days of number crunching and radar testing:

Approximate SJ radar detection ranges:

Target has 0 deg. AOB.
Battleship: 26.2KM or 28,652 yards
Merchant: 9200 Meters or 10,061 yards
Destroyer: 7300 meters or 7,983 yards

Target has 45 deg. AOB
Battleship: 3.4 KM or 37,620 yards
Merchant: 21.7 KM or 23,731 yards
Destroyer: 17.1 KM or 18,700 yards

Target has 90 deg. AOB
Battleship: 35 KM or 38,276 yards
Merchant: 25.7 KM or 28,105 yards
Destroyer: 19.5 KM or 21,325 yards

Approximate SJ-1 radar detection ranges:

Target has 0 deg. AOB.
Battleship: 34.8 KM or 38,057 yards
Merchant: 12 KM or 13,123 yards
Destroyer: 9000 meters or 9,842 yards

Target has 45 deg. AOB
Battleship: 34.8 KM or 38,057 yards
Merchant: 28.7 KM or 31,386 yards
Destroyer: 21.3 KM or 23,293 yards

Target has 90 deg. AOB
Battleship: 34.8 KM or 38,057 yards
Merchant: 34.2 KM or 37,401 yards
Destroyer: 26 KM or 28,433 yards

Personally i think the numbers are too generous. What the handicap is, is historical figures which cite the maximum reliable range. Which means, that i'm basing everything off the detection range when the target is at 0 AOB, at it's most smallest profile to the radar, and letting everything else falls where it may. If i adjusted it any other way, if the target had a 0 AOB, he'd be invisible to radar, which is obviously not acceptable.

If you'll excuse me now, i need another beer. It makes hashing all this out much more tolerable.
