Can anyone explain to me why several high fee (0.1-0.15) RingCT tx's, that did not look abnormal, sat in the mempool for over an hour unconfirmed, while lower fee (.025 ish) similar looking RingCT tx's got processed in front of them and 5 empty blocks were mined?
Unless I am missing something, this seems highly irratonal as far as miners are concerned, and suboptimal in terms of how the network is performing. It was my understanding that that there was such thing as 'fee priority', but in this instance that does not appear to be the case / is not working as it should.
The tx's concerned were eventually mined in blocks 1226464 and 1226465, and the first 3 characters of the ones i was watching were 230, 2ac, d76 and 56c. The latter was mined in 1226465 and had a fee of 0.15 for a size of 14kb, the others in 1226464 with a fee of 0.1 and sizes of 13kb. Input/output were 2/2,9/2,3/2 and 6/2 respectively.

Looking forward to an explanation that will deepen my understanding of how the network functions
