That's largely down to his first two games back though (vs Highlanders and Force), a time when there was a lot of changeover in the pack. The rest of those games the lineout success rate was above 80%:
Round | Opposition | No of Lineouts | Success Rate |
6 | Highlanders | 14 | 79% |
7 | Force | 20 | 55% |
8 | Chiefs | 11 | 82% |
9 | Brumbies | 13 | 92% |
11 | Blues | 11 | 100% |
12 | Drua | 13 | 85% |
13 | tahs | 13 | 92% |
| Overall: | 95 | 81% |
The large number of lineouts in that Force game (almost double the average) meant it really skewed the overall success rate, but it was still 81% for the period Salakaia-Loto was in, only 2% less than the season as a whole. I don't think there's any evidence in the stats to suggest he was the problem. He wasn't ever the main target though, but given Canham was going very well for most of the season and Uru has always been excellent that's not unexpected. As far as wallabies implications go the main one is probably just that he can't pair Skelton, but I'm not sure that was ever really on the cards.
Success rate also isn't everything though, and there were separate issues at the lineout in some of these games - the Chiefs one for example, we really struggled with our handover for maul setup, but iirc that was Canham/Brial to McReight, and appeared to be an issue with McReight's shoulder still being sore and a bit limited in movement coming back from the AC joint injury from a weeks prior.
