EXACTLY how much HR data can the H10 store offline?
I'm sure that question has been asked and "answered" many times over. But I am finding ambiguous information.
First, I am surprised that I cannot find that answer in the H10 User Manual ( https://support.polar.com/e_manuals/h10-heart-rate-sensor/polar-h10-user-manual-english/manual.pdf ).
(Can you?)
But according to https://support.polar.com/us-en/how_long_a_training_session_can_i_record_with_h10 : "H10 records HR data once per second and the training session can have data up to +30 hours".
What is the significance of the plus sign ( + )?
Is that exactly 30 hours; i.e. 108,000 HR values (30 * 3600)? If so, why not write simply 30 hours?
Or is that approximately 30 hours; i.e. 30+ hours, as Google A(rtificial) I(ncompetence) interprets it? If so, what is the exact number of HR values?
Or why can it be only approximate; i.e. variable? What does it depend on?
