I have used it to great effect in multiple PBW games, but it's a bit tedious, requires multiple steps to really take advantage of it thanks to the 50% cost difference limit, and is only really useful if you have more resources than space yard capacity or have an emergency.

I'm making 190K minerals a turn more than i can spend or save. I'm a trade race with lots of treaties.

By chain refitting you mean: refit to one class a little bigger then again a little bigger than the second and so on? Sorta scaling up the designs through the 50% limits getting bigger as you go.

I plan to use this on battlecruisers built from Base shipyards. Right now they take FOREVER from the starbase, but with refitting I could shave A LOT of time of them.
