Comment by @Baste-RainGames:

_ZBufferParams is listed with "x is (1-far/near)"
For clarity, it's 1 - (far / near). That's what precedence gives, but it's nice if it's actually written out like that so you're sure.

[R-033]

y is 1/cos(spotAngle/4) is incorrect in the unity_LightAtten section. The correct term is 1/(1 - cos(spotAngle/2))
