Plug-in Prime Hybrid Battery Pack Health Observations

I've been monitoring the battery pack after a full charge and just wanted to share the details.
• I forget how much Soc there was @ 100% on the dash reading ( I believe ~90% Soc)
• the cross over point is ~ 66% Soc = ~ 66% on the Dash. Obviously the discrepancy stems from the low and high thresholds for health buffers
• Run in HV mode on a full charge and Toyota's system will slowly drop you to sub 90% to clear out room for hard Regen Braking
• Hard Regen Brake sees high spikes that are flagged on the upper limits of what the battery really enjoys. 60% or less Soc on the Dash indicator and it never hits the upper threshold so < 60 – 65% is perfect.

Bottom line from my data and monitoring is:
100% = Run all Ev mode to 60% to keep the pack happy long term.
-then run HV if your going more that 33 to 44 miles and want to preserve some EV range...

Maybe its documented in the manual!? Idk/idc, I like real world experience. Thanks for your time and non hostile interactions
