Effectively - yes. Which is why it's usually even faster to jump with a decent ship.
Reputedly, there's a Fleet Carrier Owner's Discord somewhere - and reputedly, there is a script that can do the jumping for you (not that difficult, as long as nothing goes seriously wrong).
I'm on the second jump now.
It does take longer, but it's nice to just push a button and walk away for a while and come back to find 500 light years gone by rather that sitting there jump after jump after jump...
Especially with the horrid server lag they've been having lately where you'll sit in the "tunnel" of a jump for 4 minutes straight every once in a while. That is VERY annoying.
The calculator is wrong as well. It told me 68 tons per jump and it's taking nearly 80.
