Okay, so I tested the tactic with a "Tactics Test" database, places by someone here on FM-Base a while ago.
The game contains 3 controllable teams to avoid any coincidence: Tactics Test 1 (TT1), 2 (TT2) and 3 (TT3). Each team is given 50 players (every position is covered at least 3 times) with a CA between 140 and 150.
Before we take a look at the testing results, may I remind you that this only gives a brief overview of how good the tactic by itself is. There are no OP, team talk or slight changes. Do not underestimate your own input.
Ok, the results:
Test 1, season 1:

TT2 had a really good season. I've only seen one other tactic that managed to let a team end second. TT1 and TT3 on the other hand ended, compared to other tactic that I've tested, ended fairly low on the table. This is why I decided to run a second test.
Test 2, season 1:

In this test run, the tactic disappointed me. Compared to the previous test, these results were not good. TT2 dropped a staggering 8 places and TT1 dropped one. TT3 on the other hand, went 1 up. I couldn't accept this result, so I did another kind of test: I've let both tests run a second season.
Test 1, season 2:

As you can see: once the team has adapted itself to the formation, the results you get are good/very good. I was happy with the result, but I had to run the "bad" test too.
Test 2, season 2:

Although the first season wasn't good at all, this season the teams performed considerably better. In overall, they almost did as good as test 1 season 2.
Conclusion
I think that purely the tactic on its own is one of the better tactics out there. It has a lot of potential.
What I didn't upload are the fixtures. I took a look at them and I saw that this tactic crushed the opposition quite a few times (6 - 0, 8 - 2, 4 - 0, 5 - 0, 5 - 1, ...) and it never suffered a heavy defeat (except against ManU I think, 1 - 4 or something).
It's definitely worth the try!
Any questions?
