La-5fn boosted (WEP) engine time wrong?

Please review and correct the boosted time for the La-5fn from 10 to 5min.

FM report with all manuals have been already submitted in Nov. 2021:

 

In game the La-5fn engine (Ash-85fn) is rated in boosted mode (WEP) for 10min. This is quite long compared to the German (without additional injection) 3min or western allied 5min.

 

Thus far I have found that most manuals regarding the La-5fn and its engines also state a 5min time limit.

Does any else has seen any more documents than those I list, that state a 10min limit? 

 

I have compiled all primary sources stating the 5min WEP limit for the La-5fn and the ASh-82FN engine sorted from 1943 to 1954 (1943 La-5fn; 1944 La-5fn; 1945 Tu-2 Ash-82fn;1947 La-9 Ash-82fn; 1947 Ash-82fn; 1950 La-11 Ash-82fn; 1954 Ash-82fn).

 

 

Regarding the 10min time limit I have found thus far 2 credible source and one that seems questionable:

a) One source (1945) for the La-7 with M-82fn engine clearly stating 10min ( according to @=FB=VikS qualifies as a typo) and 

b)1943 report on the current state of the soviet aeronautical industry (additionally it seems to be the scource for the inlimted use of the M-82f unlimited boost)-

I figure, this is the report they based the 10min (and unlimited WEP for the La-5f) limit on (as it what used by @=FB=VikS to explain the the Yaks/Lags unlimited time on full boos).

c) one source (1944) for the La-5fn that looks like it has been tempered with and a "5" was converted to a "10" (number no longer centred between words as in other manuals) but it could also be a "15" -> which is therefore to dismiss it.

M-82f unlimited use of boost:

 

C) debateable La-5fn pilot notes

 

 

 

 

 

 

 

 

 

 

 

 

 

for those who are not able to directly spot the 5min limits in the manuals, I have highlighted those:

Thanks for the research but I can't help but think that this is the nail in the coffin for the FN compared to the series 8. Farewell sweet bird, it was nice knowing you.

why would that be? it is still  a superb low altitude fighter which I still enjoy

Because halving its WEP isn't beneficial to the plane? I'm not going to start discussing balancing. I just wanted to say adieu to the FN.

No, but it would be beneficial to reality.

Here is actually a 10min source

though I dont know how credible the source is (as its "just" a report on the current state of the soviet aeronautical engine industry l, but to my proletarian eye it looks legit),

this raises the question again, how the devs chose which manual to follow?

 

 

and this report also explains, why the devs chose to give the M-82f Engine for the La-5f unlimited WEP time:

Hi,

@Han & @Gavrick

 

will the M-82fn WEP time be reviewed and corrected with the upcoming L-7?

and will you review the M-82f unlimted WEP time also be rewied if its just based on the single mentioning?

If you have more sources I would love to see them.

Cheers
