During this epoch, our node experienced its first simultaneous block creation. We created the block but never got credit for it. In Shelley Explorer, I found that another stake pool created the exact block that we created, 13802.
As this epoch progressed, I wish I had not given such an optimistic projection for epoch 19. Our node created 14 out of the 20 scheduled blocks. The creation of 14 blocks out of 20 gave our node a 70% performance which was not good.
