Guys,
With regard to convergence and staggering\slash over laying vs. setting all guns to one range; what is your preference and findings of how effective (or not effective) it is.
For example: some with a P-51 will set convergence so as inner gun = 350, middle 325 and outer 300.
Thanks for sharing,

REALLY depends.
fighters with 6 .50's and under, I set to point convergence, range: D350
Ground attackers with .50's, I set to a zone of 100yds ending at D500
Fighters with 8 .50s (P-47 *cough*), I set to a zone of 100yds
centered on D350
Hurricane ans spitfire mk 1 are set to D300 point convergance.
Fighters nose mounted cannons I set to D 50, and for cowl MG's I have those set to D650, wing mounted set to between D275 and D350 depending on the spacing, placment and caliber (spits 8 and under are set to D275, 14+ to D350, Ki-61 to D350)
Fighters with wing cannons I set to D 350 if they're wide spaced, D450 for all 190's save the A8, since the cannons are in the wing root. A8 I have all 4 cannons set to D400.
Ta-152 and K4 have the 30mm set to D250, and the Ta-152 has the 20mms set to D 450.
110 has the 20mm's set to D500, and the 30mm's set to D350.
And then occationally I'll change to a mission-specific convergence.
All of my tank guns are set to D3200 + convergence
