My left ear is a cookie bite but I don’t find CR 1.0 to be too loud.
As far as I remember you still have a conductive loss in your left ear (and you had in your right). With conductive loss (only) there is no problem using a CR of 1.0 in contrast to sensorineural loss (this is the normal case for most people): the higher the loss the higher the CR.
For most people a high sensorineural loss means that one can hear a sound only at a certain amplification but then it is almost immediatelly very loud. Uncomfortable level ( or ) is nearly the same or even worse than for normal hearings. UCL and MCL for conductive loss can be much higher.
