Just run it again and it's 1813 I'm going to take Quadrant with a pinch of salt I think.
That's only a 2% difference, well inside the error margins.
But from before your update it was a 13.6% difference (best vs worst). That's a result. Maybe they've changed something in the benchmarking algorithm?
But apps running in the background will affect the result, also widgets and of you're doing anything with it at the same time.
