Pale Pinion year by year

Several people have reported Pale Pinion moths over the last few weeks (e.g. this one from Steve Goddard) I thought I'd see if there was any pattern to its appearances in Berkshire over the years. The numbers do go up and down a bit, but the distribution has remained scattered widely over the county. So I don't think this proves very much, but it was fun to do!:
