Your scenario is different. Your one year experience will be done on July 06. If you submit your application now you might face a rejection as you do not meet 12 month full time work requirement (till July).
Also your score were 478 prior to this bump and that falls under 483.
Trust me I had to decline 2 ITAs (18 Sep draw and Oct 02 Draw) for this same reason. My advise to you is wait for next draw and if the score drops 478 or below then you may go ahead.
It is totally your call also wait for others input too. This is just my 2 cents
