@Durkin would whoop consider an option to connect a chest strap for activities that an optical sensor is just not ideal in?

5 or 6 rides and satisfactory HR readings, today it spiked again throwing off my strain. Whoop wrist based is not accurate enough, please allow me to connect to my Heartrate Chest Strap or get HR from Apple health during activities

I will try my new whoop 5 band for my ride today and see how it‘s comparable with my Carmin setup I regular use.
*** Update *** Paying really close attention to my device placement while riding, I noticed that with hands on the hoods or on the drops, a “valley” develops below the sensor as the mussels and tendons in the forearm are engaged. Reaching over with my opposite hand, I found the devise to be ever so slightly looser over this area, which I figured might be more of a challenge for the optical sensor.
I experimented with tightening and VERY SLIGHT placement adjustment (moved it up my arm a bit so maybe a few millimeters of the tan line is now exposed, so not much). Now with the strap tension higher than what I’ve been I’m accustomed to, but absolutely not cutting off circulation or discomfort, this has SIGNIFICANTLY increased the HR accuracy to the point where I’m no longer wearing my Polar HR strap on every training/joy ride anymore. For routine Zzzzzzz training and joy rides it’s more than good enough.
In any event doing this coupled with the latest BT firmware updates (remember after doing a firmware update, delete your WHOOP on whatever device you have it paired too and re-pair it for the new firmware to play as it should in the sandbox) and using a slightly higher tension on the strap, the device is NOW starting to meet expectations
