Why has my node not been tested?

Post
LnRouter gives insights into various node metrics to choose the right nodes to connect to. To achieve this, LnRouter continuously measures nodes that pass the test criteria.
Test Criteria
Node
A node needs at least 15 channels of 2,500,000 satoshi capacity. Multiple channels to the same peer are counted as one. Additionally, 6 of these channels need at least 500,000 satoshi inbound capacity.
Channel
- The channel has at least 2,500,000 satoshi capacity. The capacity of multiple channels to the same peer are added up.
- Channel source and target nodes need to pass the node test criteria.
Only a subset of a node's channels are tested. The goal is not to test every channel possible but to test a subset to interfere the big picture. The channel selection is biased towards bigger channels.
How Is A Test Performed?
Lookups sends one 500,000 satoshi test payment in both directions of a channel. If a payment succeeds we know that this direction is able to route sats.
Scan Interval
LnRouter measures every node in a 4 week interval.
