Would tides have been more ferocious a billion years ago, when the moon was closer to Earth?

Yes, evidence from stromatolites & corals shows the early earth had far shorter days & shorter lunar months.

If we make the logical assumption that the moons mass has not changed in that time the obvious conclusion is that with a faster spinning earth & a faster orbiting moon the moon would be closer so not only the tidal range would be far greater but it's flow & velocity would he greater too.
