The Barcelona test by numbers

Greetings ladies and gentlepeoples, please find below data gleaned from www.formula1.com about the tests that just concluded in Barcelona
We know that it is incredibly difficult to glean anything from preseason testing but it is refreshing to see that reliability has improved across the grid. Hamilton’s time in the Mercedes on day 2 with the hard tyres was ominous for the rest of the field as he was 3 tenths off the fastest time set on the soft tyre with the hard tyre rumoured to be over a second slower. Oh well, fingers crossed we see a few teams mix it up at the front.
