I'm looking at the live unconfirmed transaction page at blockchain.info, https://blockchain.info/unconfirmed-transactions which currently as I write this is running at around 166,000 transactions.
When I look at the chart labeled Mempool Transaction chart https://blockchain.info/charts/mempool-count with a description of "The number of transactions waiting to be confirmed", I see nothing that goes over 50,000 and for the current time shows only 22,066 transactions.
Seems like they should be the same. One is current unconfirmed transactions and the other is the number of transactions waiting to be confirmed. What am I missing?
