Am I likely to get this transfer

So I am currently in review for a t7 clerk bid on errassign. Right now I am waiting on the supervisor to do the evaluation. The only issue is that while I do help out at the window when they are short staffed and for lunch coverage, I am not full time window clerk. I mostly scan parcel but I am at the window mostly every week. I did pass the window training years ago and my attendance and safety is nearly perfect. Only called out 1 time in 4.5 years
