I've always found the V1 speed thingy a total croc! No one can actually read/nominate this defined exact number whilst hurtling down a rwy sheez our speedo's aren't calibrated to such an accurate figure anyway!
By the time yr eyes see the V1 speed reach the line in the sand, yr brain processes it sends the req'd message to yr voice box the recipient processes that sound via his/hers ears into usable info & then via their CPU (brain) for consideration yr almost at TOC!:-) It's an arbitrary figure.
Aussie's comments are spot on re V1's def.
For me once the speed V1 has been called it's too late to stop (theoretically anyway) you go unless it's unflyable & even then it's an unknown as to the extent of major damage.
