When designing program layout you allways have to look at it as a whole and not just individual elements. The "optimal" layout for a non 3A/quad program is to repeat 3Lz and 3F and have two different tripple-tripple combos ie choose two of +3T/+3Lo/+Eu+3S the best one here is to choose 3T and 3Lo like Sasha and Anna did before quads but that seems to be harder and more risky for most skaters.This is very interesting. Because both the 3Lz and 3F are repeated.
While It seems that during Medvedeva and Zagitova era the triple-triple combinationations were more important than they are today. This is why Medvedeva had 3F-3T and 3S-3T. Which means that she was repeating the 3F and 3T and not the 3Lz and 3F.
By the way, which approach gives more points? Probably the one that has 3Lz-2T and 3F-3T?
And why Zagitova did not do 3Lz-3Lo, 3F-3T and 2A-2T-2Lo instead of 3Lz-3Lo, 2A-3T and 3F-2T-2Lo at the Olympics?
The last combo then has to be either +2T/2Lo inthe case of +Eu+3S was used or +2T/2Lo+2T/2Lo otherwise.
Add in the rest of the tripples and two 2A for the complete set.
The next thing to consider is what jumps to put in the later half and get the bonus on. Idealy you want your three highest scoring elements here. That would then be three of the four 3Lz and 3F available. Idelay the two Lutses and one Flip each with the three combos discussed above.
Puting your three combos as your last three jumping elements is of course verry risky since there then is no chance to redo one of them if need be. We have seen a few skaters attempt this and succed mostly in juniors but otherwise most top skaters put one of the combos in the beginning. All Eteri skaters for example have their +2T combo as the first element.
Putting high value elemts in the second half is however only worth it for element you can perform with good GOE even when you are tired. Thats why many non Eteri skaters have simpler elemts here since they feel they couldnt do the harder elements with as good GOE towards then end. Remember the second half bonus corresponds to approximately +1 GOE (exaxtly that for solo jumps and somewhere between +1-+2 for combos). Meaning if you lose +2 GOE when having your tripple-tripple combo late in the program compared to early on then its not worth it (See Usasheva most of last season).


Not that the change (if there is one, like you said it could be the light) is terrible, but still...more green in skating I say!
