16 Centres Ordering in Europe, page-8

I agree with this Stone.

Looking at this from a different perspective........... EU sales commenced in Nov 2013 with a 12 month target of 15 centres. The company achieved sales in 12 centres in 9 months, and has now exceeded their prediction (15 centres in 12 months) with 16 (only one more but it is more none the less) in less than 12 months.

Also the remaining 9 centres in the US have come on since USA approval obtained in February (less than 9 months ago) which may suggest that the other activity/milestone predictions may also be underestimated.

With the information from the conference of 400 units sold in the 16 centres in Europe, the average number of units bought per centre is 25. The range of sales to centres will vary greatly as some centres will only have been on board for a few weeks, with others for almost 12 months so impossible to work out an accurate usage rate, but it suggests repeat purchases.
