How many misfires does torque app report for your daily drive?

Torque was showing about 4 to 6 misfires per cylinder on a typicle 10 mile drive.
Most all my driving is city. After a 100 mile trip the misfires are down to 1 or 2 misfires per cylinder. Misfires have a random distribution across cylinders and I'm averaging 52 mpg.

I have 63,000 miles since purchasing my genII prius . It has orignal plugs, pvc valve, tires and doesnot burn any oil. And I've never cleaned mass-air-flow-sensor.

My prius like allways is running great. I was suprised to see misfires. All though misfire count is very low and not effecting anything . I just wanted to compare Notes.

My girlfriends genIII prius with 26,000 miles has no misfires reported by torque app.
