I don't know where potato came from.

As for powerlines - never used them myself, but my understanding of the technology is they're similar to wifi in many ways.

For one - the quoting of speeds. It's a TDD (i.e. not full duplex) system, and has lots of overheads. Same as when we had 54Mbps wifi and you'd get maybe 20Mbps, when they quoted 108Mbps you'd get maybe 30-40Mbps. The rating on the homeplugs is meant to be comparable to these earlier wifi standards.

You're sorta right in thinking if you get 40% of 200 you'll get 40% of 500. Of course the higher speeds depend on better quality wiring and there's losses as a result of diminishing returns, 20-30% of 500 is more likely - about 100-150Mbps.

Again remembering it's half duplex though so with 100Mbps ethernet ports you're looking at maximum download speeds of 100Mbps under good conditions, but you're also able to get 100 down, 50 up, or 75 down 75 up depending what you're doing, which is quite an improvement over the 60 you're getting now which might drop to 30 down 30 up if things get busy both ways.
