I think you guys are talking past each other.
'timeskip' typically has a certain meaning in quests. Nobody in the history of ever has taken going to sleep at one update, waking up at the start of the next update, and called that a timeskip of 8 hours.
timeskip is usually used in specific ways, and generally brushes past multiple updates of perfectly viable game time in order to skip ahead to 'the good part', hence the skip in timeskip. If Hazo is doing 2 months of training, he's also gonna have 2 months of dinners with family, 2 months of board night, 2 months of dating, 2 months of Gaku's snark. Hazo doesn't lock himself away in a chamber for closed door Xianxia-style cultivation, he's a human who does human things between training sessions.
If you timeskip past a 2 month training session, all of that is effectively lost, or handwaved away as 'it happened in the background but nothing interesting happened so just ignore it'. THAT is what roobee wants to avoid, as much as possible. If Hazo is training for 2 months, then roobee would like 2 months worth of slice-of-life updates, showing intermittent training progress mixed in with social bonding and all the other wacky Hazo shenanigans we love to read about. roobee doesn't just want to teleport to the future with a note thats says 'some stuff happened, now you're a seal-master have fun.'
Now I absolutely agree that 16 hours, or 8 before that, is a bit of a unreasonable vote. But at the same time, I understand the feeling behind it and agree that it's kinda hard to set a reasonable time limit for something like that when the whole point of your vote is that you want to micromanage (and read about) as much of Hazo's life as possible. With that specific desire in mind, what would you suggest? A day? 3? a week? At what point do you give up too much ground and realize that you just agreed to cover a year of Hazo's life in under 20 updates? (assuming multiple snips per update, a week of 'timeskip' between each snip, you could get 52 week-long timeskips out pretty quickly.)
