Personally, I see no real problem hunting the same funnel area several days in a row. You might want to consider repositioning yourself within that funnel, if possible. I do not like to hunt a given spot or area for more than 3 days in a row.........just my personal preference, but I feel that more than that I have probably contaminated that area or may have been seen by deer that I didn't see. I may go back to that area after a few days of hunting somewhere else.
During the rut, it's nearly impossible to predict where deer are going to appear, but a good funnel area is always a good bet, especially in the early part of the season when there are likely lots of other hunters in the neighborhood, spooking and scattering deer away from their normal routes or trails.
Just my opinion.
It isn't what happens to us, it is how we deal with it, that matters most.
