The speed in the csv is the value received from speed sensor. You don't need to add one by one, use a 5 km/h interval like the example, the program will calculate the intermediate values.
If you want to multiply the power, just multiply the values in the power column, for example:
Speed (Km/h),Power (W)
5,150
10,300
15,450
20,625
25,800
30,1000
35,1150
40,1400
45,1625
50,1875
55,2150
60,2450
Use the default wheel circumference (2.105 is a 700x23 tyre) and the speed from sensor probably won't be above 60 km/h.
I don't know if this is related to the issue, but try fixing that first, then if the issue persists we can do other tests.
thanks. Ok, I will test it. how many wheel circumference should I use by 27.5*1.75?

please ignore this report, I check it use app of sensor provider which communicate by Bluetooth, speed reduce to 0 too.
So this is issue of speed sensor.

The circumference is around 2.115 but such a small difference is insignificant since your goal is to overestimate power.
But anyway, don't increase wheel circumference, just multiply power values in the csv.
please ignore this report, I check it use app of sensor provider which communicate by Bluetooth, speed reduce to 0 too. So this is issue of speed sensor.
Try using an USB extension cable to put the stick closer to the sensor and replace the battery.
During riding, the power is reduced to 0, and it can't be recovered if you continue pedaling。 If you stop riding for 1 or 2 seconds, you can recover
you can check cfg file and csv file as below.

I use magene speed sensor S3+
