Fofo,
How long did it take you to kick the 1200 ft? Last time we did it with scooters it took 14 mins... I figured 1400 ft (100ft per min)... (but then again we hit the pipe...) Sometimes I take a more meandering course I guess... kinda hard to stay on course doing barrel rolls sometimes
Ben, the dive report can be read here:

As to your questions, here's my recorded waypoint info as we went along. I've replaced the abbreviations I use for waypoints with more complete names. Note these are listed as waypoint name, pressure, clock time on beach or surface/dive time otherwise, bottom depth, temp, course from that waypoint if applicable. I also list distances if I'm surveying, but generally only make hashmarks every 100' (~25 K.C.s) if I'm swimming a long compass leg. 'Beach' is before we get in the water, 'Surface' in this case is off the wall at the '13' mark:
Beach 3425 / 1412 / --- / 60 deg. F. / ---
Surface 3375 / 1428 / --- / 53 deg. F. / ---
Bottom 3200 / 2 / 46' / 53 deg. F. / 340 deg. M.
(Line)
Inner End 3100 / 3-4 / 48' / 53 deg. F. /
(Line)
Outer End 2600 / 10 / 61' / 51 deg. F. / 000 deg. M.
Barge 2500 / 11 / 62' / 51 deg. F. /
(at bolts)
Leave Barge 2400 / 14 / 63' / 51 deg. F / 285 deg. M. / ~700'
(from NW end)
Turn Left 1050 / 34 / 45' / 51 deg. F. / 240 deg. M. /
(@ small met. reef ~80'SE of Big Pipe outer end)
Ascent 250 / 48 / 30'? /

On surface 125 / 51 minutes.
As you can see I was pushing my gas, and we didn't swim the whole grand circuit as I've previously done. My SAC rate was high on this dive compared to past Grand Tours, either due to my relative lack of diving recently, the fact that I wasn't solo (I usually have an RMV when solo .05 - .15 less than with a buddy), sea-lion distractions, or any/all of the above. For whatever reason, I had to do this as a truncated version of the Grand Tour, rather than the complete one I've previously done with the same tank and gas to spare.
I seem to have a been a bit off on my course from the barge to the intermediate reefs and from there to the metridium fields proper (which we never reached). I'm not sure why; when we got to the nav. course we hit the waypoints with no problem. The good vis. would have made that much easier than normal, but my miss distances were within my normal tolerance of +-5 deg. The ~700' leg from the NW end of the barge to the intermediate metridium reef would give a maximum radial error of 58.5' or so; the leg from there to the metridium fields somewhat less. Last time I did this I hit both dead on. The tide was coming in which might have pushed us a bit inshore, but not as far as we wound up before swimming to the Big Pipe.
I would normally record data at each waypoint along the nav. course as well, but didn't due to not wanting to waste the gas. Note that I use a wrist slate for all this; removing and replacing wetnotes from a pocket every time I need to note waypoint data would be far too wasteful of time and gas.
If you've got any more questions, just ask.
