Yep, trust the calculator and put in about 50"x98" to have some wiggle room. It will end up about 9’x5’. Tyler’s type of table is great because it is easier to make an oversized frame and you only need a spoil board the size of the work area, or 4’x8’. Also, MDF can be found a bit bigger. I think there are sheets just 1" over and special places you can order 5’x10’ sheets.
