I voted between 5-10 hours if I include everything except for the time I spend on this forum both reading and posting.
That includes picking up, searching, record keeping, and cashing in.
When I tried to calculate it based on my actual number of bank stops, time at each, approx add'l drive time, and time to search, my actual number came up just shy of 8 hours per week.
102 hours/13 weeks = 7.84 hours/week
Now I might have missed a few stops or been slightly off on my estimate of how long it takes to search a certain volume, but not too far. Either way the total would be under 10 hours per week.
Now if I used my numbers from last year the time estimate would have been significantly higher as I was doing a full error search on a similar volume which would have pushed it to probably approximately double the time.
