I am struggling to understand some behaviour on a custom
7 validators solochain.
Currently using babe with a
1/4 primary slots probability, the
block time is 20 sec, and we have
PrimaryAndSecondaryPlainSlots as allowed slots.
Things i'm wondering :
- While adding log the babe module, I computed a real primary probability of arround 22.5% instead of 25% (on a "relatively small" sample of 10000 blocks).
- Also on the network, I notice a lot of fork / uncles set.
- The most problematic is this morning, I saw that a slot was missed (both primary and secondary) and the time between two block was twice what it should be (40 seconds instead of 20)
Is this a normal behaviour ? Is there an actual probability of missing a slot to produce a block ?
