John P. Cromwell attack technique on order

You can call it Cromwell or whatever you like I s'pose.

However, you should be able to use the TDC component of the PK to get the firing solution without having to draw things on the map. I know you dispatched with all that in your simplified DO'K method.... but there was a time when I mentioned that you should use the TDC component of the PK to calculate the intercept angle for you.

My initial recommendation to mimic Fast-90 was to use the TDC to setup a firing solution (close to a zero gyro angle) without having the PK continue to track the target.

I believe my exact same suggestion can be followed in this case only instead of a 20° bearing with a 70° AoB, it's 20° bearing and 35.5° AoB (or just 36°)

You're not really describing anything different here... you just forgot (or never bothered to use) the TDC to setup the firing solution as I originally suggested.

The nod to O'Kane was merely acknowledging his recording of the tactic, that both he and Morton used, which involved overriding the PK tracking and firing as points of interest passed the wire. Same thing here...

Calling it Fast-90 was deemed inappropriate because the US Fleetboat optics didn't allow for pan-and-fire solutions (which was at the heart of Fast-90).

But... I don't have any objections to you guys calling a 45° approach whatever you like.

It's all good...
