The top tier reduction isn't very scientific. We had 99% of our paying customers on the middle-tier and we engaged a couple of them asking how we could improve the top tier to motivate them to try it out. All of them said that 60€/mo was higher than what their gut would allow them to pay. In addition, we allowed Basic customers to also invoice by creditcard or subscription, which was the main feature requested for Professional. Since isn't not exclusive to Professional, that does lower the total value of that tier. If you disagree with logic, please let me know :)
