AeroPod, PowerPod and Newton

Hi there!

I recently bought a V2 PP from Masecori, but after 1 month I sent it back because the USB portal didn´t connect well with the cable and, therefore, with Isaac or with the computer to charge.

They sent me, what it seems, a used one that is the BLE version.

When I went to do the 'Best accuracy' calibration ride (after imputing all the data in Isaac´s first profile, click and hold for 4 sec PP button and pairing the sensors) I had some trouble in the process (the light didn´t do the normal yellow blinking in the start of the calibration and the numbers went gradualy from 0 to 100, then the number 50 appeared with the solid red to turn around, and then gradualy went from 50 to 100 again now with the yellow blinking. After that it started to show, what I thynk are congruent Watts for my RPE.

Could you check the ride to see if everyting looks OK?

Best regards.

Hi again John.

I just used the tool that you mentioned in another post and the Power values are very far from those of PP.

I attached two print screens:

1 - tool analysis of data at 20km of the ride (bike weight is 10kg and I input wind at -15 km/h, because Isaac shows 24,7 km/h tail wind): 152W
2 - isaac data at 20km of the ride: 257W

Why so much difference?!

When using web software you have to be extremely careful to provide the proper inputs.

You can't take a single point of data; rather, you find a place where conditions (speed, slope, wind) are fairly constant.

I looked at your ride file and selected data around the 20.2 KM mark.

In the selected region Isaac reports 244.2 watts

In this region here are the parameters:

Bike Speed: 30.5 km/h
Wind speed: 31.2 KM/h (0.7 headwind)
Slope: 0.68%
weight: 83KG total
Air density: 1.251 kg/m3
Car: 0.0067

I input those numbers into the web software. Result: 245.2W

You are OK...

Great!

Thank you John
