lipfert stated yak-3 were more dangerous than mustang (means probably only eastern front heights).

Yes, I know this quote but it is not clear for me. Further research is necessary.

barkhorn stated yak-9u as best fighter for low altitudes. he also fought 3/4 hour against lagg-3.

I am very curious how he could distinguish Yak-9U variant in the air. I do not think that the Germans were even awared of this rather rare aircraft.
His long dog-fight, although linked to Alelykhin, seems not to find any confirmation. Is there any proof that it ever occured? 45 minutes in a dog-fight should use all the fuel capacity in both aircraft!

rall stated his 109g(6?) wasn't able to catch la-5 and yak-9.

I find it surprising, it was underlined by a Polish Yak1/9 pilot Edward Chromy, that they were slower but more manouverable than their German enemies.

grislaski is quoted, that his 109 can't outturn yak-1.

I cannot exclude it but otherwise I find it quite stupid to turn with Yak when it is possible to make a safe zoom attack.
Otherwise, it is interesting to note here, that opinions of RAF pilots concerning clipped wings variant differed significantly, although the aircraft almost matched Fw 190 in roll rate (I have a graph).

general schwabedissen stated, yak-3 and la-7 were superior to 109g and 190a. schwabedissen also stated that normandie-njemen at fighterbombermissions nearly operated without losses.

I am not sure what qualifications General Schwabediessen had but generally Soviet fighters were not flown in ground attack missions because not capable of carrying bombload. This capacity was gradually introduced in 1944 but not used generally due to short range and need of every drop of fuel available in tanks. Of course Soviet fighters did straffe various targets, eg. played anti-flak role during Il-2 attacks.

at milchs meetings was stated that newer i-16 were still a danger in 9/42, la-5 has same performances than 109f4 or maybe 109g2 (1942)
i 've talked to an 190f8 pilot flew at eastern front and had at least 3 kills. he is member of the "gemeinschaft der jagdflieger". as i asked him about the truth about eastern front he meant: read pokryshkin and you know how it was.

In Poland, PZL P.11c were still dangerous if a German pilot did not know how to fight them. Generally, it looks for me more like excuses for poor performances of own airmen rather than a reliable opinion. Have you ever seen any mention that German Stuka pilots were so poorly trained, they were unable to keep in formation in 1944? This comes from accounts of Hungarian Stuka airmen fighting in SE Poland.

Jg-51 chronicle states la-5fn 50km/h faster than 190a.

You mean the book and not KTB?

NII VVS really claimed perfomance loss for several reasons. First was due bad production quality and second due overclaiming by producer. But this meant La-7 only flew "only" 612km/h at SL instead of 640km/h claimed by producer.

Just found a report 44-280 of tests of La-7 No 452101-39. It is a little bit long, so I need to re-read it first.[/quote]
