I don't have the exact answer you are seeking, but can offer my hope that you don't get affected at all. I am in the same boat - went on a hike sunday (less than 24 hrs ago). I did not touch any leaves, but who knows... I don't have prior experience with poison ivy, so I did not use technu or anything. I did a lot of reading afterwards, and am planning on using technu today. Hopefully you and I will both be rash free.
