BRouter: Respect tunnels/brides for correct elevation gain

There's been a thread in the past regarding this topic https://help.locusmap.eu/topic/31519-route-planner-respect-tunnels-and-brides-for-elevation-sums

but I want to open a new topic especially for Locus Map 4 and BRouter offline router.

As you can see on my 2 examples (attached .gpx-files) BRouter offline router isn't respecting the fact, that there is hardly elevation loss/gain on routes passing tunnels or bridges. Elevation gain calculation follows the terrain of the hill *above* the tunnel and the valley *under* the bridge - which is not correct.

1) TUNNEL:

2) BRIDGE:

BRouter itself is able to correctly recognize sections passing tunnels/bridges - but sadly not its implementation within Locus.

And since people without Locus Gold subscription have to rely on BRouter as single offline Router, the calculation should work correctly. Reliable Elevation gain is an important topic for outdoor sports, but this is not true if Tunnels and bridges aren't treated correctly.

Dear Locus team, please correct BRouter's behavior or alternatively think about opening "LoRouter Offline" for Silver-members too. A reputable outdoor App like Locus which lacks a correct working offline Router for outdoor usage (where no or just slow internet is available) is not optimal.
