no it's not negative values, cause you've to think in mathematical logic:

- * + = -

- * - = +

+ * + = +

so vtt*GTLref1-value=vtt*GTLref2

for example:

VTT=1.20 V

ideal GTLvalue 0.667% (or 0.67x)...

* = Quadcore needs a bit more max 0.7%
^ =Dualcore needs a bit less max. 0.635%

looking for idealvalue...

GTLref1= * for Quad, ^ for Dual
GTLref2 = ideal GTLvalue

1.2V*0.7x - value = 1.2V*0.667x

value = 1.2*0.7-1.2*0.667 = 1.2*(0.7-0.667) = +33 mV Quadcore
.................................................. ........... = -32mV Dualcore
