Re: Ways to deal with bogus GPS data that prevents time delta analysis

Ah ok. Yes that makes sense. While I think vertical scaling should work just fine and perhaps even be preferable to an automated solution, what about any of the following ideas: - Adding criteria to the "best match" algorithm that: - Uses direction (compass heading) to detect that the two ...

Ways to deal with track configuration that interfers with time delta analysis

Sometimes a lap will have a short period of time where the GPS data is apparently way off. (See the attached screenshot for an example.) It would be nice if HLT was able to identify that this data could not be physically possible and skip the data point or interpolate it. If that is too complicated ...

Re: XGPS160 - sometimes 1 Hz sometimes 10 Hz (v20 - iOS 9.3.1)

Hey John, I've had that happen before on rare occasions. A min or two before heading out check your rate in the GPS view. If at 1Hz, try power cycling the GPS. That's fixed it for me before.

Re: 60fps video recording on iPhone

I'll second this request. I want the high frame rate so that I can watch my autocross videos in slow motion to more easily analyze them.

Re: Enhancements to lap analysis charts

Just want to re-iterate my request to have dynamic scaling of time difference OR have the value displayed along with the other values with the cursor. See the attached image. I would like to know how much I was ahead on the lap before I spun. The only way I can do this currently is to manually edit ...

Re: Curves analysis Delta time

Harry, sorry to revive an old post, but have a further question about time difference calculation between laps. How do you deal with laps that are a slightly different length? (E.g <15m) Do you use the average of them? Or do you use "time from start" and "percentage of lap complete&qu...

Unexpected Multicam behaviour

I use HLT for autocross. I recently purchased an iPhone 4s to use as a multicam. For autocross, I like to manually start the video and let HLT start a new lap when crossing the actual start line. With multicam running, I start the video while staged and both cams start recording. As soon as I pass t...

Re: iOS 9 Testing?

I also (foolishly?) upgraded to IOS 9.0.1 and am often experiencing the same issue where the screen appears to be "zoomed in". Not just on the video recording screen. It has happened on the main laptimer screen as well. Though usually shifting to the opposite orientation and then back corr...
