Get 2 planks, lay them face to face, clamp them together dead centre so the gap created by the bow is equal at both ends, measure the gap an divide it by 2 to get the amount of bow per tile. If its more than 2mm, its technically out of tolerance to comply with BSEN14411.
But with the correct layout you should still be able to get round it without it causing lippage. Could also have some levelling clips on hand for the odd tile here and there.
