it takes them a few days to extract the HSFX mods and copy them into their package

No, that's a different thing.
UP takes HSFX as a base, widely untouched (that's why you can select the HSFX compatibility mode from JSGME for online gameplay).
Additional UP packages reside in the files folder whereas the HSFX base is available in SFS format.

Actually it is both IMHO

They take items from the HSFX release and use it in UP as their own, P-51s being a perfect example. And they also provide HSFX as a standalone mod.

Kwiatek makes hollow claims about UP being more accurate That is to say all he provides is words stating that it is more accurate
He provides no proof of it

The discussion is pointless.
Regarding FM historical accuracy, Kwiatek is doing what he can do to reveal the facts his work is based on.
He's doing a great job for that matter and I guess at the moment there's nobody available who has got the knowledge and time to compete (or, better choice, complement).
But that's not the point.

All excuses/reasons aside the fact remains that Kwiatek makes hollow claims about UP being more accurate That is to say all he provides is words stating that it is more accurate

Criticism about Kwiatek's work mainly arises from editing other people's work without asking for permission, thus claiming ownership of things being intellectual property of somebody else.

Agreed that is one of the main but not the only

Further more working on FMs always shifts the balance in regarding missions - it's something you can greatly disagree about whether or not it's more important to have historical accurate FMs or balanced gameplay. History wasn't balanced in the air, at least from a specific time on, but there might be reasons that IL2 gameplay should persist balanced yet.

None of the issues I have commented on had anything to do with balance

...only a few of those are UP FMs, and those show the same error tendency like the HSFX ones.
The same thing, more or less pronounced, nothing to worry about.

Agreed

But the point your missing here is that did not stop UltraPack from claiming to have a more accurate P-51 flight model.

At the time they made that claim they had no issues with such claims

It was not until after I took a closer look and noted that the opposite was true

That HSFX's P-51s were more accurate

That is when making such claims became an issue over at UltraPack

On a related note..

Have you been watching the UltraPack forum?

They accuse AAA of controlling the content of the forums

Yet that thread at UP has been un-locked and lock so many times I am having trouble keeping up with it

But here is the sequence

Lock and Unlock sequence
1 HaDeS locks it and calls me biased
2 HaDeS unlocks it an deletes his post
3 I post thanking HaDeS for unlocking it and deleting his previous post
4 HaDeS deletes my post thanking him for unlocking and posts telling me to stay on topic
5 Kwiatek locks the post
6 Someone unlocks the post to allow Gryphon to respond and than locks it right after
7 HaDeS unlocks the post to post than locks it right after
8 JG54_Emil unlocks the post to post than locks it right after

For a locked thread it sure gets a lot of post made to it

But only post from the UP crew

Also note that before they lock the thread

They use it as an opportunity to accuse me of something

But I don't get to respond to their accusations because the lock the thread

But that is not surprising

Pretty standard stuff at the UP forums

What is new

And rather funny

Is after HaDeS accuses me of all sorts of things in his post

He has the audacity to end his post asking me to start another thread and show them how to do the correct IAS to TAS calculation!

LOL!

Can you belive that?

Now normally that would be too funny

If it was not so sad
