Here' are some numbers:
My own report is BFRO 59757 and was submitted on July 29th, 2018 (day 210 or 155 to end of year)
Kansas Report BFRO 62405 was submitted on Jan 19th, 2019 (day 19 or 174 days after my report was submitted)
62405 - 59757 = 2648 reports in 174 days, a little more than 15 per day, or roughly 450 per month.
I don't know how many reports were published in that total time, but here are the months I know. It's averaged 8 per month since December.
Mar 2019 = 3 (so far)
Feb 2019 = 6
Jan 2019 = 12
Dec 2018 = 11
Total = 32 (or 8 per month)
BFRO takes in 450 reports per month and publishes 8 per month (1.7%)
Today there are 5160 BFRO reports in the SSR database.
5160/62405 = 8.26% BFRO reports published vs submitted.
