Thanks for the comments.
Regarding the table, I initially tried it the way you'd like it to be, but the shape of the available space didn't allow me to do that (put the "O2 remaining" labels as part of the header). I tried it with the decompression levels as the rows and as the columns, but either way, there was a space issue with either the labels or the cell contents for the level effects. I could have run it horizontally across two panels, but then I wouldn't have been able to do what I wanted with the map, or I would have had to break the timeline up across two panels.
Sometimes, you just have to abandon standard gridded solutions to use the available space effectively.
Same with the decompression times. I thought about listing one time and then saying "When hatches are unsealed, decompression times for the full ship are 10x those for a single, sealed section." But that actually takes up almost as much room as just listing two numbers for each and I decided it was more user-friendly to just give both.
That was definitely the part of the layout I struggled with the most, because it's a lot of information and an awkward amount of space for it. It's interesting that I've now had one person say it was their favorite aspect of the layout and then you say it's your one complaint. It's definitely the most non-standard, which I guess is why opinions vary.
