Average depth wouldn't look anything like those numbers. I would say considerably more than half of the bottom times for those dives were spent in the 30'-40' range, occasionally even as shallow as 20' -- except those times where I dawdled down the wall for some reason; Mary's Place, Calvin's and Valley of the Kings come to mind.Does your box give you the average depth that would go along with the max? That would be a great bit of info, as well.

(I haven't been able to get the JTrak software to successfully "talk" to my Uwatec Tec 2g computer because the USB IrDA device I already have doesn't seem to be supported by JTrak on OS X, Uwatec wants me to buy their $99 version instead. I keep meaning to buy different IrDA hardware or fire up one of my old Windows PCs and try SmarTrak but haven't been gotten around to it.) I'll see what I can do this weekend...
