Eve of the Big One

So here we are. It's the evening before my second degree-level statistics exam in 3 months and the time where I wonder how I ever got myself into this mess. It's not the maths it's the conceptual stuff I struggle with. I mean, how does Rsquare change resemble a semi partial correlation? Can anyone tell me? Actually, can anyone tell me?

Anyway, it's foot to the floor tonight. Talking of feet and floors, just done my run...new record round park of 16:38. Feeling very pleased.

I'm hoping the analogy of running performance and general performance holds.

I love you all like prize winning micro art.
