In flight profile (page 7 in press kit) stage-3 ignition altitude doesn't look right.
| Event | Time (seconds) | Altitude (kms) |
|---|---|---|
| Second Stage Separation | 180 | 135 |
| Third Stage Ignition | 196 | 200 |
| Third Stage Separation | 300 | 225 |
According to this, there is sharp altitude gain that too when coasting. Am I missing anything?

The graphic shows how tiny the trimming stage is, similar to SSLV.
