Hi Robbie-Rocket-Pants,
For every take off there will be a spread of V1s.
V1 GO will allow you to suffer an engine failure and still accelerate to VR.
V1 STOP will be the last point you can safely stop.
Practically V1 GO can't be lower than VMCG, and V1 STOP can't be bigger than VR.
Your CTOP has probably selected a V1 midway between V1 Go and V1 Stop.
