Just upgraded to the mg and doing some side by side analysis with a chest strap HRM. Overall the mg is very accurate and inline with the chest strap except for several drop outs when I am getting to a high heart rate. This is an outdoor cycling workout on hills wearing the Whoop on bicep. On the wrist I found Whoop to be very inaccurate while cycling with my wrist position. Have a look, and any feedback or advice on how to prevent these drop outs is welcome. And the “wear it tighter” is unlikely to be the solution as I generally keep it very tight and it was under a tight jersey. Whoop data in Blue and chest strap in Purple.
