So what dates did you collect since last summer? I've done this here in the thread earlier for the timeframe 2011 - 2014. Would need to look it up again. Then we can complete the number of fill-up and do some calculations.
Since 27 jun. 2014 , 25 oct. 2014, 27 feb. 2015, 28 jun. 2015 and 23 oct. 2015.
Sorry it took me some time to answer. Had to check those to be sure. So continuing with this, next one on 20 something feb. 2016.
But now, that she knows we know, she may change this, just for fun...
