There is no reason to have gap in research cost 6k, 12k, 24k => 200k.
That gap make game science cost multiplier is useless.

Suggestions:

1) remove 'Ignore tech price multiplier'
option just reduce science cost 1/4. but its not intuitive.
and mod already have science cost multiplier. they can be merged together...

so,
make basic research cost cheaper (x3-x10) times (6k=>2k) (12k=>3k) (24k=>5k) (200k=>20k)

make multipliers range in (x1-x64) - basic (x1-x16) * (x4) to compensate science cost reduction and removed setting "Ignore tech price multiplier"

or (x1-x1024) for what ever you want.

2) remove bob_coefficient as there already research cost multiplier and map research cost multiplier.
with bob ftl-theory-* cost is 2M !!! that already too big.

with mod research multiplier and map research cost multiplier - research cost going incredible...

That 2 setting enough to nerf bob late game.

added little mod for it https://mods.factorio.com/mod/SpaceMod-byOswald

Totally agree. With full lab productivity (+160%) FTL engine requires 770 sattelite launches.
It takes me ~8 hours to research single FTL stage with game.speed = 4 and 7 science/sec (which is pretty good for angelbob if not using cheaty modules I suppose), and, the most important - by the time you reach FTL theory you have everything built and done, so you have no fun waiting several days in game.
And the FTL engine is heckingly cheap compared to it's research cost or protection fields.

You can already turn off the satellite cost altogether, but ok, I will take this on-board.
