Really nice to see I'm in the meaty part of the bell curve. I consume a normal amount of gas, but gas consumption consumes an abnormal amount of mental energy during my dives. I can't significantly change one but I can change the other.

I am often in the skinny end where gas goes away quickly. Deeper in a drysuit tends to get through gas quickly. The divers who stay down an hour or more all seem to ues enormous tanks around here. Or are small women who have gills or don't breathe or something.

For us technical nerds, what are the actual mean/ mode, median, standard deviation?
You've got enough data now that they are probably fairly meaningful and stable.

Thanks for asking.

The choices are ranges rather than discreet values. The median (midpoint value) and mode (most frequent value) are easy, they are both 0.5-0.59 cu ft/min or 14.2-16.9 L/min.

I calculated the weighted average using the midpoint of each of the ranges and the number of votes for that range. This may not be entirely accurate, but it is the best I could do. The current weighted average is 0.55 cu ft/min or 15.7 L/min. So, sorry, no std dev.

Yes, these values have remained constant/stable for a long time now, since at least 2021

Wow, there have been 22 more responses to the 2016 poll since the last update. This is probably one of the most active polls on SB. Remember, you are able to change your vote in this poll if/when your average RMV changes. In the 2016 poll, the median and mode are both 0.5-0.59 cu ft/min. The weighted average also falls in this range. Thanks for all the responses and posts
