Trying to figure out how you pulled this off.
The first, and most important factor, are your "MAD SKILLZ", and that should not be underestimated as a contributing factor.
Second, is I reviewed the Mk. based wave multipliers
1 1.5
2 0.9
3 0.7
4 0.6
5 0.5
Now, thanks to the linearization of fleet ship types, we can compute the "expected relative strength" by simply multipying the columns together, which yeilds
1 1.5 1.5
2 0.9 1.8
3 0.7 2.1
4 0.6 2.4
5 0.5 2.5
That seems reasonable, though it may need some adjustment.
Then I realized that The Core gets a .5 penalty to wave and .3 to reinforcement numbers. Is that applied
on top of the Mk. V wave and reinforcement penalty? If so, that would actually make The Core much easier. In fact, the relative expected strength would be 1.25 (2.5 * .5), which is LESS expected firepower than normal AIs
Mk. I waves. True, it isn't quite that simple, due to factors like centralization of firepower and the immunities Mk. V ships get, but still that may need to be looked at.
Three, the map type, spokes, is a pretty trivially chokepointable map type, something it seems that was key for this victory.
Also, lol, won with only a Armored golem (and your homeworld, of course) left in your name.
