Are you able to try (temporarily) switching to wasp-os and looking at the graphs in the heart rate app?

Infinitime and wasp-os use the same (relatively simple) algorithm but wasp-os will visualize the (cleaned up) data as it is captured. This would offer you some clues about what is going on. It certainly helps uses see when the sensor is doing it's thing properly.
This video is slightly out-of-date, you now have to upgrade infinitime after restoring the original bootloader, but if you want to see how to get the graph from wasp-os (and how to get back again) then take a look at:

PS I really must get round to adding an (optional) raw heart rate sensor capture tool to wasp-os so we can capture data from a wide range of users. The current algorithm was developed and tested against 100 separate captures but all data originates from exactly one test subject (me). If people are getting round to hammering on this stuff now then being able to capture a large range of samples to work on would be very helpful.
