It is quite common in our breed for the levers to shoot up very fast once they start going up, they don't often follow the norm of how it is supposed to happen :-)...
But then they don't always do that even if they have done it the last season.
Maybe she will start proper bleeding very soon to make it easier for you.
I would test on day 7 maybe just to make sure she is not close to getting there and prepare to travel and be near the stud from day 9 ready if the levels do what they did last time :). Or just travel there well and early and test once there as travel can affect the levels (slow the rising)
That way you are unlikely to miss the right time :-) Good luck!
