And how does pack weight effect that time?
I have been trying to get an estimate of the time it would take to get from one location to another in the park.  A big part of that is the time to do portages.  How much difference in time difference is there between crossing with a pack and the return trip. So to find out how long a portage would take I timed my self while walking my dog.  I wore my GPS and found that the rout I take is 2.69 miles.  The course crosses a couple of ravines and has 2 large hills to clime. About half of the rout is un trail woods. It is easy walking woods but not like a path or trail. I started with no pack and then added a pack and progressively added weight.  I changed packs in the middle of the test because I thought the other pack carried better.  
Pk WT Lb.       Mi      Time Min            
0                 2.69      55            11/14/09
24                 2.69      59            11/15/09
45                 2.69      74      Raining& stopped 2 times to adjust
                                               BluePack      11/26/09
45                2.69      77      Wet but dryer than yesterday. Green pack fits better But Compresses chest      11/27/09
57                2.69      76      Better adjusted pack Dryer than last time      11/29/09


Although a heavy pack slows me down it is not as much as I would have thought.

Man I wish I had some peoples free time.

OS,

Try telling that to my son ,Mr Evinrude. We should be more like S2 and take pictures on the portages.

The average person walks 3 MPH unloaded. Including load and unload time, over the years, my observations have noted that easier portages seem to work out to 2 MPH, average portages about 1.5 MPH and ugly portages (Fern to Olifaunt at days end in 80 degree weather:)) 1 MPH or less. In my travels, the majority of groups that I have seen double portage so the length of the portage must be multiplied by three. Using 320 rods as one mile one must do the math from there. BUSHWACKING though is an entirely different story. All bets are off and all calculations out the window.......as you and KF already know. You and KF both have my respect

"Although a heavy pack slows me down it is not as much as I would have thought."

think again though, about the cumulative affect of that heavy pack - you only carried your pack once on your test- now double that for each portage, and then throw in a big fudge factor for the 10th portage of the day, maybe for the third day in a row.  Though I agree with taking one heavy load for the first of two trips, and the lighter load for the second trip.

Double tripping the portages, I guess I use a 1 mph rate for the one way distance, more or less.  I'm a fast walker and can do the return trip for load #2 at better than  3 mph - a fast pace for a woods trail, and probably for the most part, can keep to a 3mph pace while carrying the gear (note that those are light loads though)

But I don't just use the 1 mph rate -- what I do is assume 10 min unloading, and 10 min re-loading - that includes moving the canoe to shore and tieing, and setting it back in the water to laod again.  No it doesn't always take that long, but over the long haul, it averages out - that gives me some time to take pics, or do whatever.  So I plan a minimum of 20 minutes, even for a simple 10 rod portage (regardless of the fact that it won't take that long) - then I add the 1 mph rate for the distance, more or less.  That way, if I take time to saw some deadfall out of the trail, or can't find the start of the portage, or the water is too low, or there are new beaver ponds, or the portage landing is really crappy and takes twice as long as normal to deal with, I have some extra time built in.  For me, over the 8 or 10 portages I'm likely to be doing in a day, it does average out pretty closely to what I've planned.  

About the same as using 3mph for paddling - it averages out over a long day.  And I rarely finish my day early, normally I'll be about on schedule or I'll br running behind due to headwinds, or difficult portage conditions.

I do what you are thinking of, that is, I plan an itinerary for each day so I know how to get from point A to point B in 3 days travel.  Then I fine tune to adjust - maybe for getting to a certain spot on day 3, I'll have to make day 2 longer than originally planned - maybe I'll have to get up an hour earlier, and or travel a lot later, but at least I have a plan that will get me where I want to be, more or less when I want to get there.  That works about the same for a solo trip or tendem or group trip, though group trips will definitely be slower.


edit: if that didn't make sense - for a one mile portage, I'd use 1 hour, plus the 10+ 10 minutes load unload time for a total of 1 1/2 hours.
