placement matches ranked gaming

if you win all 10 do you think there"s anyway what so ever you should be placed in bronze 5 the lowest of the low or do you think if you win all 10 is should be bronze 4 in the worst case scenario?

Or maybe if 10 win will still be bronze 5 then it should skip placement for those players after all 10 wins in row would be enough to get to bronze 4 and then it wouldn't take about 20.
