Hello,
I don't think this is a prediction, it is a result for last month, which only means that 75% of finalised application in last month have been precessed less then 7 months, 15% between 7-9 months and 10% above 9 months, but this is average time so it means that maybe for application with documents in state ready for decision that time is 2-3 months? We don't know why that time was that long, maybe it ws related to missing documents ? So no worries
