I know Jano road tested it with AFR system fitted but cant say i know what the figures were. Understand why your asking though as this would explain wether its a fuel starvation issue above 5k?

Even borrow one of another perfectly running car if you can?
Also what about pulling one lead off at a time and connecting it to a spark plug then revving the engine stationary and seeing if the spark disappears after 5k revs, trying each lead in turn?
If it does at least that may tell you what cyl the misfire is on if it's ignition/spark related
Not a bad idea mate, worth trying when im next with the car

Cant say ive heard of anyone running less than 0.6 but worth a shot to put spark plug possibility to bed

Just ordered your 4 sensor webber kit off your site. Will whack the new phase sensor in and check gap and most importantly fit the proper crank sensor.
I fitted a new cheapie one from that Brands Hatch performance company and cant help but feel its the cause, will soon know.
I took the saph out saturday and got a good 5 minutes of boosting up to the redline before the 5k missfire kicked in, so would make sense to be heat based? god knows really
