R = 0.3994 × (1+B) × (1.0045)^T × (1+0.003A) × (E - 0.34P - 4.5)
The wonderlevels (A) (and especially expansions (E)) carry great weight to the SS (R) of a "hardcore" endgame tournament highscorer, due to their wast amount. But the impact of a single wonderlevel or expansion deminishes with city size.
I´ll use my own live cities as an example:
City A: 116 expansions and 116 wonderlevels (coincidence)(I can´t remember how many of expansions are premium, so set to 0)
+1 wonderlevel:
(1+0,003*117)/(1+0,003*116)=1,0022255
+1 expansion:
(117-4,5)/(116-4,5)=1,0089686
City B: 70 expansions and 32 wonderlevels
+1 wonderlevel:
(1+0,003*33)/(1+0,003*32)=1,0027372
+1 expansion:
(71-4,5)/(70-4,5)=1,0152671
So getting the space and building the Mountain Hall (or any other AW) will have a WAY bigger % impact on my small city (I will have to build relatively more troops to do the same tournament encounters).
Mandatory research (T) have the same impact on all cities (0,45%).
Max. production boost from relics (B), have a big % impact on small cities, but soon becomes a constant.
I must admit, that I don´t understand, how the formular should favor small/mid cities in any way
Not using your space in the best way, building the wrong AWs and so on, is a block around the leg of a "hardcore" tournament player. But it´s an even heavier block around the leg of a smaller player
The formular DOES favor those, who have their AW-levels gathered on a few highlevel AWs, rather than divided on many lowlevel AWs. But that fall under "not using your space in the best way".
Plz don´t get me wrong: I´m glad, that the formular don´t favor small cities
Just don´t claim that it does
PS. I´m fully aware, that many ppl would have made other choises regarding their city, if they had known the formular back then.
PPS. I´m NOT saying, that I agree with the scaleing of the formular (nor the scaleing in difficulty between provinces, for that matter). I´m only saying, that it don´t favor small/mid players over big players.
