"Good tactics and bad tactics can always have different outcomes. If you do something well, I think it is considered a good tactic. And if you don't do something well, it is considered the opposite. So it definitely comes down to execution of whoever is doing anything."
Jakob Ingebrigsten
Hocker wins one big race and now he is the "greatest tactician of this era". I think you need more data points to make this pronouncement. Unfortunately, championship level racing doesn't provide a lot of data points! His execution in the Paris final was superb. But Hocker was 6th in Tokyo and 7th in Budapest. Why did he finish so low in these events if he is such a good tactician?
I think Grant Fisher (different events I know) displayed better tactics throughout his Paris campaign. In both the 5K/10K, he stayed near the front of the pack--always in contact with the leaders. He never led the race, rather he conserved his energy. When it was time to ramp up for the final 800 m or so, he was in position to strike. He didn't have to move up through the whole pack to position himself for the final lap (like Gebrhiwet in the 5K). Fisher only came away with bronze (twice!), but I think his tactics maximized his performance.
