I just am not sure if "crab jump" would not be more efficient (It would definitely lose the property that changing frobenius would not change the reallocation).

Hmm crabstretcher dirty seed requires 285 gliders ... it is a close race.

Simillar drawback would have an allocation by a corderhip ... where I am not sure how much "time" would be wasted in waiting mode.

But seems for this distance the Cordership would be the winer ... so no funky temporary binary arm reincarnation.

So here is target creation by Cordership. I have slowed the recipe by 2 bits, each moves the crash by 288FD, we could shift it by multiples of 16FD
by slowing stopping glider correspondingly, but moving reflector (to empty space) would be similaly expensive as moving the target. The method is about 100-150 glliders cheaper then the one using slow^3.

Finally I have decided to slow the recipe just by 1 bit, currently I am working on cleanup (automatization) of east part of the fuse to be intermixed with rebuild and mainly to be done from the west ... (when east debris are still in the way). After passing this obstacle it would be rather easy to finish it.

[Hippo.69]

Seems fuse arm and ecca1 program is completed.
There are wrong bits when ecca1 was stopped, and ecca2 "not started yet", but otherwise it looks rather well.
(Probably corderpuffers should be stopped a bit earlier to match V4 perfectly).

puffers stop

The combination of cleanup with rebuild is working, but it is not optimized considering the arm block movements.
Defragmentation of the final recipe could save some bits ...

BTW: I have checked how much important is defragmentation and how much agnosticization on ecca2 building salvo ... but it was probably already mostly defragmented. Further defragmentation, reduced ship size by 13056, and agnosticization by further 149568.

Seems finally ECCA2 is started correctly and puffers stopped exactly as in version4 (several off 1 errors corrected).
So changes of ECCA2 program could be implemented ... 1 glider small change in near cleanup, probably different ECCA1 destruction (definitely not building the ott), change in near seed (path of final glider) ... including change in far program ... firing last cordership from the other side.

[Hippo.69]

For the slow^2 salvas, I have decided to extend my set of honeyfarm moves.
This was another incentive not to use BFS and switch to IDA (BFS exploration has a drawback, that you can not reasonably save state of progress, while IDA has no problems with it so now, I can interrupt and restart(continue) the search whenever needed...)

Similarly I have changed my golly beam search to beamIDA for the same reason. Now I can work on glider salvo destructions allowing the interrupt and restart(continue) ...

... (in beamIDA we remember evaluation on the position beamwidth for each depth in the tree and we cut at each level branches exceeding the evaluation) ... there is an interesting improvement in the beamIDA ... when all paths reaching current IDA level use the same prefix, we can fix the prefix and the new depth search neednot be started from the root ...

... and I am finding more efficient recipes while widening the beam ... OK finaly width 128 gave the same size salvo as width 80 ...

[Hippo.69]

I have not optimalized ECCA1 destroyal, but remaining portion is optimalized as I was able to.
After 0e0p (how many years?) I would return to binary arm optimalization (and ECCA1 replacement).
Now it finaly become the bottleneck of the construction ... I bet the slow salvo for yellow lane version would be significantly smaller (with trash agnosticised one color version) and the binary arm efficiency could be 30-40% improved ...

The fuse arm glider cost is about 500 ECCA gliders (ECCA1 and ECCA2 efficiency are equal), binary arm glider cost is now about 12 ECCA gliders, but I expect it to be about 8 ECCA gliders at the final version.(V1 reconstruction was so inefficient that fuse arm glider cost was about 2000 ECCA gliders).

Early stages are fine to replay at 8^5 speed, then 8^9 works well.
The puffers could definitely be stopped earlier. Probably even before west fuse reconstruction, but this would probably change when ECCA1 would be started earlier.
