I will continue what I left unwritten this morning.
The initial assumption in the topic seems completely wrong to me.
As I heard from Askinadz's interview, the institute paid money only for difficult hikes.
Since Igor Dyatlov went on 9 hikes before his 5th year (each winter+summer) and did not receive a salary yet, there was a problem with the availability of money.
It seems to me that they just wanted to go on a hike, but the hike does not reach the level of difficulty.
From Korolev's interrogation, it is clear that a difficult hike is 350 kilometers,
but for Dyatlov's group, 300 km were allowed.
Further, of these 300 km, they traveled the first 30 km by truck, 20 km with horse = a total of 270 (250) km.
Delays on the way are also unacceptable, because this means additional food, additional money and cargo.
Dyatlov's route itself seems strange (artificial) to me.
For proof, there is an assumption that no one has ever gone this route either before or after.
The mystical expedition of 1999 (an expedition for TV reportage) only went halfway along the ridge 40 years later and they shortened the route to get to Vizhay on February 12. Thus, this route could not have been completed in a short time.
I think that Dyatlov could have gotten to Vizhay only on February 16, when he should be WANTED already.
The group of Karelin and Blinov also had a circular route.
I do not know how popular circular routes are and it is difficult to imagine what caused this in 1959.
I myself have been on circular routes - only when the second half of this route is by transport.
Perhaps the requirement of the city route commission is not to go beyond the borders of the Sverdlovsk region.
But the route from Vizhay to the Dyatlov Pass, to Otorten and further beyond Otorten is popular.
