"Time to target" data source not working properly

Hi there

I think the "time to target" data source has a bug.

When I use it in my dashboard, it seems to generate random numbers about how long it will take to walk to the end of the route I'm following. The "distance to target" field and the "average speed" field work fine, so why isn't the "time to target" just the distance to target divided by the a average speed? See example in screenshots. Also, on a hike I did a couple of days ago, after about 1km following a 22km route, the "time to target" said the remaining walking time to complete the whole route was 44 minutes.

I'd be really grateful if you could try and fix this - or perhaps tell me if I'm doing something wrong.

Many thanks

Adam
