Good news,
someone Bitmain Technologies Ltd. put up some nice graphs to monitor the fullness of blocks (not blockchain.info, but I hope you can give others a chance as well).
https://www.btc.com/en/stats/block-sizeOf the past three months it shows
- the median daily blocksize
- the average daily blocksize
- the number of daily transactions
- the sum of daily blocksize
It also shows monthly graphs for all time as well. I think that once the median monthly blocksize hits 1 MB, it can be said that blocks are definitely full. For the first three months of this year it was around 933 kB, or 93%.
I know that the party line stipulates that many if not most of the transactions are spam and shouldn't be counted. But that's a different topic.
