"In order to develop _Subsurface_ in a way that serves its users in the best "

"_Subsurface_ after using this software for a week or so, a one-box user "
"survey pops up. It is entirely optional and the user controls what, if any, "
"data are sent to the _Subsurface_ development team. Any data that the user "
"chooses to send is extremely useful, and will only be used to steer future "
"development and to customise the software to fit the needs of the "
"_Subsurface_ users. If one completes the survey, or clicks the option not to "
"be asked again, that should be the last communication of this nature one "
"receives.  However, if one's diving and/or subsurface habits change and one "
"wishes to provide another survey, this can be done by launching _Subsurface_ "

"particular moment in time) as a red overlay on the dive profile. Ascent "
"ceilings arise when a direct ascent to the surface increases the risk of a "
"diver suffering from decompression sickness (DCS) and it is necessary to "
"either ascend slower or to perform decompression stop(s) before ascending to "
"the surface. Not all dive computers record this information and make it "
"available for download; for example all of the Suunto dive computers fail to "
"make this very useful data available to divelog software. _Subsurface_ also "
"calculates ceilings independently, shown as a green overlay on the dive "
"profile.  Because of the differences in algorithms used and amount of data "
"available (and other factors taken into consideration at the time of the "
"calculation) it is unlikely that ceilings from dive computers and from "
"_Subsurface_ are the same, even if the same algorithm and _gradient factors_ "
"(see below) are used.  It is also quite common that _Subsurface_ calculates "
"a ceiling for non-decompression dives when the dive computer stayed in "
"non-deco mode during the whole dive (represented by the [green]#dark green# "
"section in the profile at the beginning of this section). This is caused by "
"the fact that _Subsurface’s_ calculations describe the deco obligation at "
"each moment during a dive, while dive computers usually take the upcoming "
"ascent into account. During the ascent some excess nitrogen (and possibly "
"helium) are already breathed off so even though the diver technically "
"encountered a ceiling at depth, the dive still does not require an explicit "
"deco stop. This feature allows dive computers to offer longer non-stop "
"bottom times."
