Since October's summary for the botanic gardens in Edinburgh has now been published on their website, I can now report the final totals for October for that station taking a rain day to be one where 1 mm of rain or more has fallen, which are as follows:

Monthly Total For October: 75.6 mm (Expected), 53.2 mm (Actual)
Number of Rain Days in October: 12.4 (Expected), 13 (Actual)

We had 70.4% of our average October rainfall and 104.8% of our average number of rain days in October, so that month was 29.6% drier than average according to the actual rainfall amounts, but 4.5% wetter than average according to the number of rain days.

2017 Autumn Total: 139.3 mm (Expected), 115.2 mm (Actual) (As of the end of October)
Number of Rain Days so far this autumn: 22.6 (Expected), 26 (Actual) (As of the end of October)

At the end of October, we had 57.2% of our average autumn rainfall and 76.9% of our average number of rain days for this autumn, so this autumn was 17.3% drier than average according to the actual rainfall totals, but 15.0% wetter than average according to the number of rain days at that time.

2017 Yearly Total: 581.4 mm (Expected), 621.2 mm (Actual) (As of the end of October)

At the end of October, we had 88.2% of our average annual rainfall, so this year was 6.8% wetter than average at that time.

As we can see, the botanic gardens in Edinburgh were wetter than Edinburgh Gogarbank during October and since it has a lower average October rainfall, the overall drier than average anomaly was also much smaller as well.
