Assuming no one changed an already-cast vote within that time frame, then you got a 5. (106*7.0283)-(105*7.0476)=5 (within rounding error).
Edit:
The general formula , for when more than one vote may have been cast is:
(Vf*Sf - Vi*Si)/Vf-Vi
Where Vi and Vf are the initial and final number of votes and Si & Sf are the initial and final scores.

Solve for x
[(105 * 7.0476) + x]/106 = 7.0283
x=5

your score ≥ 7.0283
my score ≤ 5.9
x = I hate you.
Can you work out what score I'm going to give you? |
