Impressive! I didn't expect there to be any simple activation for the drifty portion of the oscillator, much less a 1G activation.

By the way, that C4_1 statorless p33 reduced to 56G trivially:

Nice! Is the route a result of something like a retrosynthesis? As a synthesis apprentice I've wondered a lot.

The procedure I use is a bit complicated, although it ultimately boils down to "subdivide and conquer". If the final object isn't stable, I tend to work backwards until I find something much more stable. (If this new object is an oscillator, it's usually either made up of several small separate easily-synthesizable components, or else has a much larger stator than necessary, specifically chosen to allow for the final step to occur. This may happen multiple times.) Once that has happened, I find that I set myself several waypoints between empty space and final object to effectively outline a potential synthesis. I choose them so that from each waypoint, getting to the next waypoint seems nontrivial but still likely. If I can't find a close enough waypoint, I tend to mess around with some of the waypoints to see what sorts of useful transformations can be made, which sometimes leads to unexpected but still useful results. Of course, some waypoints may end up going unused, as some easy-looking transformations can actually be quite difficult. Finding appropriate waypoints is a skill that can really only be improved with practice.

As a second data point, Extrementhusiast's description is roughly what I did for Bullet's p10, albeit in fewer iterations. I conceptualize the process as a search for finding synthesis predecessors that build motifs that "look hard" out of other motifs that "look easy", which can be taken one at a time like the waypoints idea. Once there are no "hard" areas left, the remaining amount of retrosythesis to do isn't challenging. The main obstacle in Bullet's p10 was constructing the highlighted patch of cells here, for example.

I have a file of useful syntheses of common objects, and one of those syntheses for the R-pentomino just turned out to fit snugly, with zero half-diagonals of clearance. The blocks can also be inserted with two gliders, again with 0hd clearance. So, p98 and p196 in 66 and 65 gliders:

Going back to school, I'm caught in LWTDS. For my 900th post I'll write about my horrible attempts in synthesizing Metamorphosis II.
It's a compact p60, and injecting the two LWSSes/gliders is problematic for a synthesis apprentice. Anyway the first half is easy:

Unfortunately, the central 64-cell still life would almost certainly be very hard to construct.

As a side note, there's one soup for the oscillator on Catagolue, but it's not really any help, as expected, since it forms at generation 1:

Note that the caterers are flipped with respect to the canonical ones on the LifeWiki, but this version is employed in larger oscillators like pi orbital and Hans Leo hasslers.
The same caterer recipe is useful for the syntheses of p60 and p90 pre-pulsar hasslers as well, but a suitable activating reaction for the latter is yet to be found. On the other hand this method is too expensive:
