Rides and routes elevation problems

I'm a bit concerned about the karoo2 ride calculations.

To sum up, I designed a route on strava, then same route on karoo dashboard, and ride this route it using karoo2. 

These are the data they show me:

Strava - 93.08km 1.987m ascent

Dashboard karoo route - 93.2km 2.451m ascent

Dashboard karoo ride - 94.4km 2.002m ascent

Dashboard karoo ride opening map - 94.4km 2.451m ascent

as you can see, there is a huge difference between ascent for the same ride. What should I trust? karoo2 unit matches strava, but what is happening with your own dashboard maps? This is a very big difference for me, more than 450m on a ride done with your own unit.
Is this a known bug? Are you planning to fix it? I have this same issue with practically all routes I plan on karoo web dashboard.

 

Thanks in advance.

  Hi Ruben,

  I spotted this already in December... and others as well... 
  Obviously the HH recommendation at this time is to plan your route either in Strava and then import to K2 via the dashboard or plan your route in the dashboard and import it to Strava to make sure the elevation data are accurate...
  
  Best regards

  Hi Andi, thanks for answering, I remember that I saw this issue spotted before, but can't find it in the forum.

  Thanks for the link. I hope this will get fixed as soon as possible.

  BR.

  Ok, I know hammerhead is aware of this issue with dashboard, but they say on the "known bugs section":

  " Dashboard does not display accurate elevation/Ascent numbers when importing certain routes from other platforms; No Known workaround as of now. It will be fixed in one of the upcoming releases. "

  I traced a route on strava, then exactly same route on hammerhead, pointing over the map on both platforms.... and I'm sure it is not an import from other platforms bug, is the way someone is calculating elevation gain... I really want to trust hammerhead (everyone will be a super-pro cyclist with "everestings" every week ) but I think his estimation is not correct at all, I'm sure othre platforms make mistakes too and are not 100% accurate, but this is the result on the same route, pointing over map on strava and hammerhead dashboard I got:

  

  

  +2.026 m on strava

  +3.301 m on hammerhead

  Someone is cheating XD.

  I forgot to say, that the same route above, if I import from strava without pointing manually over hammerhead map is:

  +3.446m

  Something is broken here. Hope you can fix this soon.
