Always getting a mismatch between number of pictures from Micasense and events files

We have recently started to explore Emlid M+(rover) and RS+(base) for implementing ppk solution for the data captured via drone employing Micasense rededge camera. Every time we do survey, we are encountering a mismatch problem between the number of images and events captured. We would like to invite your suggestions and feedback regarding this.

I am attaching logs from two of the test

  1. Test with drone flying at around 30m height at slow speed. (Micasense has 357 images, events has 360 events)

  2. Test with drone kept static on ground (Micasense has 458 images, events has 399 events)
