After using my FR 265 for 7 months with no problems, after the last update 3 days ago, my HRV scores have skyrocketed. My average used to be in mid 30s; now the readings are close to 100. There has been no significant change in my lifestyle so, this sudden increase in HRV measurement seem to be the result of the upgrade. The overnight HRV readings used to be a zig-zagging but continuous line; now it is a scattershot of various discontinuous points. This faulty HRV measure has been distorting my training readiness score too; making the watch increasingly useless for the original purpose I bought it for.
