No, we are not wondering whether to set 1013 or 1013,2 because PANS-OPS clearly says (as stated above) it is 1013,2; full stop.
1013,2 is 29,91978 inhg so using 29,92 is PRECISE. 411A is not happy because of a cowboy nature, but because he is right.
Before we frown upon this pee-sized 
0,2 hPa let's not forget that:
- at FL380 0,2 hPa equals to 17,4 ft ref: Manual of the ICAO Standard Atmosphere Doc 7488
What would you, captain, do to me when ATC say QNH 29,58 and I just dial in something that, upon closer inspection, reads 29,60 ? [17,4 ft approx ,019 inhg]
. . . . 
. . . . Yes sir. No sir! Thank you sir.
JAA TGL #6 Guidance material on the approval of aircraft and operators for flight in airspace above FL290 where a 300 m (1000') VSM is applied :
- At the point in the envelope where the mean ASE [altimetry system error] reaches its largest absolute value that value should not exceed 25 m (80 ft);
- An automatic altitude control system is required capable of controlling altitude within ±20 m (±65 ft) about the selected altitude
Supposing that I keep 1013 at FL 380, my AP features something called "SOFT ALT mode" and will ignore variations +/- 50 ft. Added together to 67,4 I may have busted the certified aircraft RVSM envelope. Certainly by a very small value, but intentionally 
.
This post is a mire of bull-poo because, as thankfully pointed out by HF3000 at #37 below, eventough 0,2 hPa is 17,4 ft at FL380, changing the sea-level reference of the altimeter by 0,2 hPa would only make a 5,5 ft difference on the readout. FD.

And now for
THE REAL nit-picks:
1013,
2 / 29,92 or 1013,
25 / 29,9213?
Manual of the ICAO Standard Atmosphere Doc 7488: Sea level atmospheric pressure P
0 = 101,3
25 x 10^-3 Pa.
PANS-OPS 1.1.1.1 : Flight level zero shall be located at atmospheric pressure level of 1013,
2 hPa. Consecutive flight levels shall be separated by a pressure interval corresponding to at least 500 ft (152,4 m) in the standard atmosphere.
Solved.
