I don't understand that a product oriented for software engineer use sentence like "Significantly improved startup time" instead of real numbers. What does that mean "significantly"? 10%...50%?

like lots of software, a lot of that can depend on plugins, themes, how many buffers are getting re-opened from the previous editor state, etc.... I imagine it makes it hard to produce meaningful numbers outside of extremely controlled test cases, and might be misleading to some people.

They should just compare the startup time of stock versions of 2 and 3 and post those.

That would probably be a good middle ground. You will still get people saying "what the hell, mine take 3 seconds to start up with 10000 plugins and 20 1MB files open, but you say 350ms?" But, can't please everyone.

I think values like that are more often used by advertisers, instead of software engineers honestly. It's incredibly tricky to measure the increase of start-up time as a percentage since it matters so much on hardware, what files you have open, if it's cached, etc.

Using a single percentage would probably be more misleading than just saying "significantly improved".
