Current state:
Slots BTC Person
1 4 Goat
1 4 nextnonce
3 3.5 btctree
1 3 Goat
2 3 edd
I will keep the one at 3 and the two at 2.5 and place one at 4 btc
This is confusing and reduces the total amount of your bid... Probably I will ban this kind of thing in future rounds.
Not really. If you processed the order all at once, you'll see that he had to reduce the 2.5 part to 2 simply because of lack of slots.
He was basically stating what the current state of his bids were. From what I understood, he could have just placed an additional bid for one slot at 4 BTC and accomplished the same thing.
