I like that your process for calculating how long you could last appears to consist of multiplying the amount of time others can last by their ratio of working ears to yours. Science!

As I read his comment I was going to write basically what you did, but I thought "No. No, that is too nerdy." So thank you =D

Relevant: I do wonder though if the disorientation would be less for someone with complete deafness in one ear. I would think that they are already somewhat used to the balance/orientation issues.
