Looks like 5 plates which is 495 with bar then 70 then 50 then 20 and finally 10
u were right on the 5 plates 585 then 2 35 70 then 2 25 50 then 2 10 20 ten 2 5 is 10 so in end 635Did you add the bar twice? 6 plates x 90 = 540 + 45 = 585. I'm guessing 35+25+10+5 =75. Plus 5 plates. 450 + 75 + 45= 570
