OK. I was diving with a Galileo Sol and Suunto Vyper as backup and one time our SI was a little short of the 1 hour the Vyper likes. It was 50 minutes or a little less. The Suunto gave me huge penalty on the next dive and in the end went into deco and with the Galileo having lots of NDL time I surfaced locking out the Vyper for 48 hours.
