We have the question Time to prepare for EVA out of ISS that has a good and complete answer about the hours to days long process to prepare for an EVA from the ISS. My question is just about getting into a suit the fastest.
There are a lot of variables, full gravity, micro gravity, suit style, pre-fitted vs first use, available assistance, and probably other I have not considered. While all that the prep for an ISS EVA is important, some people like to compete, I imagine that there has been study and competition for space suit donning time. This question seeks to identify speed for a Le Mans start
When the French flag dropped to signify the start, the drivers ran across the track, entered and started their cars without assistance, and drove away.
When it comes to donning safety gear competition is a frequent tool used for building muscle memory. Anyone who has been in the military has donned their gas protective gear multiple times in a race against the clock and their peers.
So in my hypothetical scenario we have two or three astronauts, who are competing for fastest suit donning. They talk among themselves, each picking the their preferred suit, it is theirs and fits perfect, they agree on a venue (the ISS or Earth, or whatever) and agree to have some number (maybe zero) of assistants for each of them.
The winner must be safely and fully suited, vacuum ready, and move under their own power some short distance to a finish point (airlock?)
Where do they decide to have the contest? What type of suit do they pick? Do they have help? Who wins?
