Sure, you were probably thinking I’d wait to 10 days apparently (or just under that being the placement of ‘bets’) but I am back in 2 days or whatever.
No the 10 day mark was semi-arbitrary and in no way reflects the bookies belief of when the return would actually take place. You see the 1:1 odds anchor had to be set at some point on the scale in order to use a sliding scale method in the first place and save me from listing out each and every possible bet and the associated odds. This was necessary because it would only be possible to create bets on how long it would take you to return rather than a straight "will he return? Yes/No"
Placing bets on whether or not you would eventually return would not be interesting because everyone already knew you would (an easy prediction to make given not just your history but your nature).
