This is really me testing how to upload an image, but for fun here's my chart on the data from 2013. and thanks to those who post the data, I find it very useful. I have been taking the post nearest the end of each month, then calculating the average number of units installed over the intervening days. That daily average can be multiplied by thirty to get an estimate of a (30 day) month as there are no true monthly figures. All in all, over the last five months the average installation was 22 units per (30 day) month.
