Instead of the term annual average, use the term:

average year-to-date

The listener (or reader) will then understand this is just an estimate of
the annual average, improving as the months go by.

I have a rolling average graph that starts Jan 2004 and is updated every
month - there is a benchmark, rolling average and than an annual
average.....my problem is that I don't think that annual is the correct word
because annual means year total and the end of line only equals 7 months.
Please help me find the right word or let me know if i'm overthinking this
Thanks
