Not sure about other types but the G650 can have a different V1 to Vr both for BFL or V1 min data. For example departing LFMN with the current conditions this morning (15 degrees, wind 080/18, dry runway). At 103,600# take off weight with BFL V1 136 kts, Vr 140 kts, V2 148 kts. Select V1 min numbers and we get V1 112 kts. Vr 140 kts, V2 148 kts.
Lower the take off weight to 80,000 BFL V1 113 kts, Vr 117 kts, V2 133 kts. For V1 min numbers V1 108kts, Vr 117kts, V2 133kts. Selecting V1 max numbers V1 and Vr will be equal.
