What is the estimated time loss for an egregious error?
Time loss is a consequence of an error but not the error itself. So I don't think an error becomes egregious or not because of the amount of time lost (or lack of any time lost, for that matter.)
Ok. But how much time do you think that egregious error cost you?
J-J, Swampfox exist outside of time. Answer to that question depends on your relative speed.
Do what I do now and just blame the map!
