Ocampo-Russell's cutting-room

On topic of the Ocampo / Russell Earth-Mars p-h-s-i cyclers, I am still working on those. I believe I have nailed down the set of h up to 3. But. I could not help but notice some cyclers as did NOT make it into Table 4:

4-2-2-5 (r 2): 1.45 AU; 1.12 turnratio; vinf 4147 m/s. angles 92 x 4

Unsure what the authors' dealio was, with 4-2-2-5. This 'un weren't pounding a new one into the planet. Mars at 1.38 AU should be seeing this guy.

UPDATE 6:40 PM MST: Deleted that dumb poast where I'd picked the wrong angle for my turnratio. Gotta pick the longest one(s) or they'll mislead 'ja.

UPDATE 3/26: I should delete this dumberer poast. 4-2-2-i was already handled: it was 2-1-1-i. Whose fifth solution is just Uphoff's backflip.

At least it's an opportunity to improve the R-O algorithm. To whit: if (s > 1 && p % s == 0 && h % s == 0) continue;.

And yet... 3-1-1-19 (r 2): 2.18 AU for 1.43 ratio; 0.9 turnratio; vinf 5434.24 m/s. angles 94.82 x 2. Turnratio a bit low?
