Reg-rec was overcharging and I've replaced it with an aftermarket unit.

I've been carrying out the usual tests and thought I'd do a leakage test. On that front there is a dispute between Messrs Suzuki and Haynes

For the leakage test the workshop manual specifies no more than 1mA whereas the Haynes says the limit is 0.1mA. I'm getting 0.2mA.

I definitely got 0.1mA the last time I did this test over a year ago. I've recently changed the headlight and indicators and fitted a voltmeter (hence the overcharging discovery). Disconnected all that and still getting 0.2mA.

Not a problem according to Suzuki but something I should be investigating according to Haynes. Who should I believe?

I've also checked the continuity on the stator. Both manuals agree on 0.2 to 0.55 ohms. I'm getting 0.7 ohms across all combinations of the three yellow output wires and no reading to ground. They're out of spec but not by much and, as all three are the same, is it worth worrying about?
