How long have you had your Clarity and how many miles on it? Mine is a 2018 Clarity PHEV Base built 11/17 I purchased it late February 2018 so I am coming up on a year. Several unplanned long trips have me sitting at 18449 miles. I ended up giving up early in keeping track of power and gas due to the level of effort required to log it every night. I was logging kWh used miles and converting kWh into gallon equivalent to log into the EPA’s tool which then gave me MPGe. This was WAY to much work.
