Load Balancing Percentage or number of transaction

Thanks I was reading from the link below where we can put a range of 1 to 100. I only need a small percentage of around 5% to go to Node C.

1) In the scenario a total of 60 transaction comes in, would it only go to Node A and B first ? 2) Can I put 4.5 ? does it accept decimal values ?
