Yahiko being 15 isn't entirely off, Suigetsu was 16 and 177.4 and Jugo is 18 and 202.4, Jirobo was 14 and 181-something. Besides Jiraiya as we saw Ibiki wore the same stuff the Sannin wore during the end of the third war, we can assume it was something that was worn though-out the third war period, and I guess that means Minato became a chunin first, then Jiraiya left for war and ended up being the Ame Orphans Sensei for a short time. Yahiko was 8, Nagato was 10 and Konan was 10 when they became Jiraiyas students according to the new info. We have to just suck it up and add it somehow. Also Tobi has always been shown a good bit taller than Zetsu(177.0cm) so 175 I believe was the true error in height. 182 fits him better.
