New cal ride

Hi I have changed my PP location so wanted to do a new set of cal rides across my three bikes so deleted profiles by reset unit in Isaac. Set up first bike, cal ride worked well. Downloaded details and then set second bike as active profile, but as I have seen in the past the cal ride didn't go the ...

Re: Calibration effect

Thanks for the information If I have 3 profiles for seperate bikes (all mounted in same position on handlebars) are the following set of numbers acceptable as aero/windscale/friction/tilt, or should I be recalibrating any? Is their a specific numerical equation that when these numbers are inputted s...

power average vs NP

Hi When i look at a downloaded file my average power differs to the file my Garmin uploads. I was wondering does the isaac software include or exclude zero power time in the average calculation. my NP values are far closer, only a few watts difference, but aerage power can be 20% off. Secondly, uplo...

Calibration effect

Hi After reading nearly every article in the forum and a lot of your assistance, could you explain what calibration actually does in real terms, given the PP is continually rechecking the mounting angle every 90 seconds? If this is true, and the accelerometer is accurate, what purpose does a calibra...

Re: CDa estimate

Apologies. Let me clarify. If the app calculates my cda at a value 0.032 for the parameters input, what variability could it really be i.e. would it be 0.032 +/- a fraction, , or could it be a wide range and the value given is just a best guess. My question really is how much error can be present in...

CDa estimate

Hi How much variation can you expect with the CDa estimation value vs what real world may be...if you add your height/weight/riding position what is the likely range of value in the real world vs the 0.032 the software estimates (for my size), can it have a significant effect or is it unusual that i...

What does calibration set

Hi When you do a cal ride, is this only to establish the wind scaling and angle, does a calibration modify any settings not visible in the profile section? When we do a check calibration is this just modifying those data field just on the basis of a longer distance and therefore more accurate data c...

Re: No power reading on edge 820

Apologies for the late reply. I see dashes not zeroes. As per previous post i have made on this one, perhaps one ride in 10 the values appear, no matter which order i turn the units on

BTW any chance you will put a version out for regular PP that just has slope and wind on?

Re: PowerPod V3 transmits slope and wind too!

I still can't get this to display except directly after a cal ride (on garmin 530). I have tried rebooting multiple times after first connecting to powerpod, change from Bluetooth the Ant connection and back again, none of which works.

Any ideas where to go next?

Re: Analyze Wind?

So when drafting and the wind effect comparison is used, and shows (say) net minus 25, it doesn't mean a 25 kph tailwind, it means the bike has an effective net benefit equivalent to 25kph tailwind.

I guess I wanted to know how to read that wind effect comparison correctily

Re: Effort animation

The graphical line plot shows speed in kph but the animation bars on the right are showing different numbers at same point. E. G. Line graph at 40kph is showing 28 kph on bar display at side, the values don't match as if kph is being converted to mph even though metric is selected

Effort animation

Why does the effort animation not track the same value while animating as the speed shows on the graph, e.g. riding at 40-45kph on graph reads 28-30kph on the animation bar for road speed, all rides show the same difference.
