Estimated Value Sent : 2.0 BTC (more)
"Estimated Value Sent" excludes known change addresses.
For example, let's say we have a single transaction where address A sends 1 BTC to address B and also 1 BTC back to address A as change, then only 1 BTC is estimated to have been sent.
Proper use of a new change address for each transaction (like all HD wallet implementations) obfuscate this feature.
