Mileage of your TB

Hi all,

first let me say this: tb-run.com in general is working fine and the daily updates from geocaching.com are running like a charm ;-).

In the last year, we did not have a single occurence where tb-run did a wrong calculation of the ranking – (as long as the information from gc.com was up to date and gc.com provided the right results).

Most of the mails regarding wrong ranking we get, can be tracked down to the fact that the race tye is set to a “fair” race. This which will filter out movements by the same geocacher. You find a detailed explanation in a previous blog post.

However, there is a problem right now:

As you all now, tb-run can only work with the mileage that is provided by gc.com. Since a few months, we experience a problem that seems to be related to what gc.com is showing.

We recognized that the mileage delivered from geocaching.com all of a sudden changes from time to time. Example

  • For this old TB that was not moved since 2010, the log from 08/14/2008 shows 32.16 Miles – which is correct. Now two days ago, at 1:15 CET gc.com showed 5259.59 for this TB. And an hour later gc.com showed 377.03 Miles.  At 3:15 then it was back to 32.16 Miles. At 9:15 it was 464.04 Miles for two hours and then it was correct.
  • Or this Race TB from BNJanny (Upsstups)
    Log  from 01/17/2017 in Cache Kosinus meets China. Correct is 0.15 Miles. Yesterday all of a sudden gc.com showed 5266.23 Miles. One hour later it was back to 0.15 Miles.

It seems that these are not exceptions but this happens across geocaching.com.

We have written a program that pulls the mileage from gc.com every hour for several TB’s to see if we can detect any pattern. We are also checking if this is somehow related to tb-run.com – but don’t think so at this point.

We will update this post once we have any news – hopefully in the next few days.

If you have seen similar behaviour, please leave a comment. This may help us to track down the root cause – or give us more meat  when talking to Groundspeak.

Update of Rankings

Due to changes on geocaching.com, the mileage of certain TBs is currently not displayed correctly on tb-run.com. This is relevant for race types “distance fair”, “long jump” and “Race to cache”.

We have fixed the issues today (May 8th). As soon as the TB receives a new log, the mileage will show up correctly on the following day on tb-run.com.

Sorry for the inconvenience

 

tb-rescue und tb-run… the current status

Hi all. I know, I did not send a single life sign during the last month. Neither in the blog, nor as replies to your emails.

But I was completely snowed under due to private and business projects.
Originally I planned to use thewinter season to implement many ideas for tb-run and tb-rescue and be able to proudly remove the “beta” label from both sites.

But what can I say… I did not and still both sites are running with almost no issues.

I have the impression that 90% of all “my TB is stuck” cases are covered by the current tb-rescue technology.
The service has become well established and seems to be stable.

We receive lots of new rescue requests every day and our server sends out thousands of mails every day to potential rescue teams in the relevant areas. Seems like the western caching civilization is mostly covered – see Map.

The banner ads from Groundspeak on gc.com do supply us with new interested geocachers every day and we have exceeded 8000 registered users.

What else is on the todo list?

Well, first of all we have the topics that are most aksed:

  • Watch more than one area
  • Have nice statistics about the races
  • And my main issue that tb-rescue does not handle some processes too well.
    One example is: if a TB owner does not mark his trackable as missing, even though a rescue team has confirmed that its gone –  (sigh!).
    In this case, the rescuer does not get a rescue point and the request is kept open forever.

Ahh.. the „most Wanted“ functionality is still the creation of rescue request for TBs that are stuck at another CACHER.  🙂 .

For this, please also read “Rescue a TB that is stuck at another geocacher“.

Well.. Other than that… The situation at tb-run.com is even better: Everything is working fine.
By now we have more than 500 races with over 3800 Trackables in total.

We dont have a standstill, improvements are just postponed 🙂

Thats it for now, Yours sincerly, Sascha
(currently crossing the atlantic during a flight… having some time to let my mind wander….)

Why does the mileage of my TB not show up correctly?

Update 30.July

After groundspeaks last update to gc.com the mileage bug should be fixed.
In case you still experience issues please try a “Recalculate Distance” first.
If there are still logs on gc.com where the milease is missing please let us know the public TB code.

We will now start the update process that updates all races. Should be done by friday morning (2.July) latest.

Hi all,

since groundspeak did the last update to geocaching.com at the biginning of june 2010 we receive quite some complaints from you, asking why tb-run.com shows the wrong mileage for a TB.

Here comes the short answer

Due to a bug on geocaching.com we are missing the mileage of the last log.
As soon as a new “placed” log is added to this TB, the previous one is considered as well.

In detail:

tb-run.com does not simply use the total mileage that gc.com shows for a trackable. This is sometimes not correct but even more important:  This number has all mileage – but we must only read the mileage that occured during the race of the TB (from start to end date of the particular race).

Thus, we collect the individual mileage that is shown behin every “placed” log – see screenshot:

And exactly here the bug on geocaching.com hits us.

For some reasons, in some cases the last log on gc.com does not show any mileage.
gc.com does consider it in the total mileage figure and it is also shown in the Google Maps Vie (“View Map”).

However, on the TB overview page that tb-run.com alway the mileage of the last “placed” log is missing- see Screenshot:

Our experience is, that also a “Recalculate Distance” does not solve this issue.

But:

As soon as a new “placed” log is added, the milease of this (now last but one) log show up. Again,  the mileage of the new log is missing (and so on).

We have informed Groundspeak about the issue and they have promised to work on fixing this.
Until then, we have to live with the problem.
