You're both right here, to be honest... the idea behind the test TPU does and the one you see elsewhere focusing on specific game events/locations is different.
- TPU wants to show the maximum potential FPS in game X on CPU Y, and how each processor ranks in that maxed out scenario - uncolored, 'scientific' value. A window into the maxed potential with regards to high FPS gaming. Keep in mind those CS GO players used to run 4:3 at low res and super low settings... They like this test and it serves a purpose in their buying decision - and rightly so, I might add. It is also here you see Ryzen's improvement over last gen in all of its glory.
- Specific game location tests serve a night and day different purpose; they show us the worst case scenario for a CPU. Does it run maxed out? Yes, but it also runs into a badly optimized, or heavy in asset/code part of the game. This gives us a window into the worst frame drops per game per CPU. It also tells you mostly just thát: how does it work out in that specific game. This is interesting for people who play mostly that specific type of games. TW3's Novigrad or AC: O's towns, same type of game & same behavior on CPUs.
Different purpose, and I think both approaches are valuable to readers. I also have to say the 720p testing fits well in the rest of the review for TPU because there is zero focus on minimum FPS. Its all about averages, ballpark idea of relative performance. Not a deep dive.
