i think it looks fine but i am not doctor.
usually when u just wakeup, the bp is quite low as the heart beat just increases from lower state from sleep.
maybe u can also add in before and after meals to confirm the bp, additionally the time of day. i find that immediately post meal, the bp tends to be higher when insulin are released.
u also can add comments on what food u eaten, lots of carbs or salt intake /carb intake etc, then u can draw inference from the pattern if not then ur spreadsheet is quite flat without additional details for your own analysis.
make sure the line is in the middle where it can "feel" the pulse as there is where the main veins or arteries are.
