The graph is from the TsAGI report and is seems to be a clean Su27 with 18920kg gross weight (50% normal fuel load
Edit: Looks like not a clean configuration as the same 3000m curve is much lower than that in the 27SK manual.

Not in all documents…In this case, the instrument speed is indicated separately…It is also fully written-true/instrument speed…
Spoiler
13 min roughly equals to 50% normal fuel loading. I guess it’s used for testing by the devs.
if it is indicated, it is much closer.
Also 3000m is a bit lower than 10000 feet and 35000lb is around 60% internal fuel on F-15.

No!..see my post below and read carefully … in this book (this is not the RLE Su-27SK)-THE INSTRUMENT AND TRUE SPEED ARE DUPLICATED BY TEXT AND FORMULA…The charts show the true speed.I underlined the text and the number of the graph drawing…
In this table, it is incorrect for the Su-27…
Spoiler
yes though its important to note the Su-27 carries way more internal fuel is 27% internal fuel in the Su-27 is gonna last a lot longer than 27% in something like a F-15 or F-16, for reference Su-27 at 27% has a little over 2.5t fuel while the F-15 at 60% has about 3.2t
It’s only 158 feet difference. It’s pretty close.
Yes!..
From 27SK manual, it’s tank 2 + tank 3, totaling 5220 kg. So 50% means 2610 kg.
Эксплуатационная вырабатываемая вместимость топливных баков (при γ=0,785):
• бак № 1 – 3180 кг;
• бак № 2 – 4160 кг;
• бак № 3 – 1060 кг;
• бак № 4 – 1000 кг;
• ВСЕГО – 9400 кг.
8.2.1. Предусмотрены следующие варианты заправки самолета топливом: полная, основная и частичная. При основной заправке заправляются только баки № 2 и 3. При полной заправке заправляются все баки. Заправка баков производится закрытым способом – под давлением или открытым – через заливные горловины. При частичной заправке бак № 2 заправляется открытым способом полностью (контроль визуально) или не менее 3400 (контроль по топливомеру). Топливо из баков вырабатывается через расходный отсек бака № 2 автоматически. Порядок выработки топлива регулируется системой топливоизмерения СТР7-2АК.
And from TsAGI report posted above, 50% normal fuel loading equals to 18920kg gross weight. Try calculating with 50% full internal fuel.

yep, just saying
Incorrect…This is a clean graph…There are two others…
Spoiler
What for?..I gave examples of the angular velocity of the U-turn!..
This weight is 18920 kg…It is necessary to add the weight of Pylons and R-27/R-73 missiles…

Because you are using a TsAGI graph, and this graph is for a clean Su27 without any missiles. This is not a graph from the 27SK manual, which include missiles.
i remember 12 months ago saying exactly you were saying when i was shooting R60s at high alpha, and i actually agree, i think the physics simulation is off but it’s easy to get used to, you essentially have to assume that missiles will always dive towards your flight path after a high AoA launch. R73 is by far the best missile for these shots though, and delaying the launch and holding AoA longer would have killed more speed and brought the actual path closer to the one you expected, not that this was the issue here. without flares i’m sure it would have hit

yeah but with that weird physic the missile is forced to work way harder to hit someone than it should, so it’s a bug that will harm shots like this when pulling high alpha or doing the cobra maneuver, imagine wasting all of your energy for one shoot but the missile simply goes in a totally different direction than the one your plane is pointing lol

No, I don’t use the TsAGI schedule for the Su-27…In general, this document is most likely for students of the Zhukovsky Academy…For the Su-27, graphs are used based on the Technical Operation Manual No. 10, Book 1…
Spoiler
just gotta shoot later so you’re slower, or lead the target even more, it’s kind of like leading to the left or right of a static boat/tank because you’re on the move
i think it would be better to fix the bug than adapt to it

they change the color of a tree and that causes a missile somewhere to become heavier by 5 kg but only on weekdays, i don’t want to imagine what would happen if they changed any core element or anything physics related lmao
