One thing that we discovered while trialling ChartMate PRO on the ATP Tour is that many of the coaches are computer phobic. Some of the very well known coaches were actually terrified of computers and stories about needing someone else to print your email out so you could read, dictate and then have someone else type the response, were not uncommon. The most reluctant coaches said it took 1 or 2 video taped matches to get the feel of the programme before charting live matches. Those who were a little more comfortable were charting effectively after about 2 sets. In general we found that coaches were delighted at how easy the system was to use and was countless times more efficient that using pen and paper.
