Where the gap comes from
Two scores side by side say one is higher. This says why: the score is a weighted sum, so it comes apart, and each component’s share of the difference adds back to the difference exactly. Compared against Tenderly, the highest scorer of those selected.
TenderlyvsBlast API
+8.4points
- Latency+8.5
- Head freshness−0.1
- Availability−0.0
- Correctness+0.0
The parts add to +8.4, exactly — the score is a weighted sum, so it comes apart.
TenderlyvsCloudflare
+38.5points
- Availability+29.7
- Head freshness*+9.4
- Correctness−2.2
- Latency+1.6
The parts add to +38.5, exactly — the score is a weighted sum, so it comes apart. Components marked * were measured for only one of the two; the other’s weight is spread across what it does have, which is why the two sides can carry different weights for the same row.
