I think what you are saying is close to 60% of the class of 2008 who started in 2008 finished in 2008… I find that hard to beleive.
Then if you say there was 180 thru hikers at this years adz and that means 220 or so who started did not show up at adz. Keep in mind that there is a fair number of hikers who never reach Aqua Dulce so well Donna know how many folks she sees she counts noises not boxes, say 20 & of hikers get a second box at WSs that would make the count different then how many showed up…
Every year a fair amount of hikers from previous years jump on the trail north of Campo and go all the way to Canada. That makes them thru hikers indeed but may not be 2008 hikers. Having kept records of hikers who made it to Canada for over 10 years i can tell you its a slippery slope to know exactly.
I agree perhaps that the PCT has the highest ratio of finishers but i am not so sure of how many do it in a single year. Then again maby i am wrong on this, there is after all no one sitting in Manning Park checking off the list from Campo. Andrea may know how many folks she gets but not how many skipped whole sections to arrive at her place…
