How do you define 'small'? And as far as I know Iwona is definitely not small. Or are you saying that list is using the measure mentioned below?
I was referring solely to the patterns discovered by Rokicki. I agree, Iwona is not contained within a small bounding box, though it's not particularly large either. I didn't really attempt to answer your question about Iwona and Lidka because I don't know the answer, but I suspect it would have involved some targeted survey of combination of small patterns based on long lasting interactions which had been previously discovered.
Rokicki said he improved a few items in the list, while he also included Iwona in the list. I'm confused.

Can anyone please link to the Russian Herschel Displacement article (I forgot the author)?

I think you meant this article about the Pi heptomino by Nicolay Beluchenku:

Iwona was already known, it's not one of Rokicki's improvements.

Aha, yeah, it's Pi displacement - I somehow got it wrong.
Yeah, but his improvements are significantly different from Iwona. He also mentioned the reason he excluded arks is "not compact enough". Now I wonder what's the definition of compact?

Thanks for the synthesis links. After examining the synthesis for 31P8H4V0, I found a few improvements that reduce the cost from 189 to 182 gliders (See Small Spaceship Synthesis thread)
The 33-bit block-dragger has syntheses; here are my 12-glider one from 2015-09-01 (top),
which improved your 13-glider one from 2009-09-22 (bottom):

In 2010, Paul Tooke
built a similar device, but it uses sqrt-layers, so it only grows at t^3/2. Still, it would be fairly easy to add a slow-enough gun (Simkin's with a few semi-snarks?), write a glider-pair script, and maybe rebuild the whole thing with modern technology to make it smaller and cheaper.

You are going to need to define what you mean by "distinct p2 rotor types".
I've cataloged 7811 distinct P2 rotors in sizes from 2 to 118 bits, although lots of them are a single object supporting disjoint rotors.
