I recently acquired an SmO2 sensor and was able to connect it to my Wahoo Bolt. When I upload the data to TP I can display a scattergraph of the O2 saturation levels by time but the graph seems to round off all the data to whole % points rather then displaying it to the tenth of a percent as is found in the data. The actual data contains three decimal places (ie. .495 or .503 these correspond to 49.5% or 50.3% respectively). However all the scattergraph points just show the whole percent and throw away the last decimal value so the graph is not very revealing to look at since all values from .1 to ,9 are all displayed as the same. It would be much better to allow this data to be displayed with full precision vs making someone purchase WK04 to see it. BTW I did purchase WK04 for myself but my coach was not using it and therefore could not really see the data and this is a disappointment.
