The [only] difference is that you'll have the most TPS resolution the closer you are to the top without going over. Going over = dead space and a flat spot at the top of the TPS range. .99 or lower will get chopped up into reference intervals by the EEC at startup. The closer you are to the top the fewer intervals will exist. The difference between intervals at .99V and say, .80 volts is [not] 10%. It's considerably less.
If I remember correctly, you might squeak out one additional interval toward the top of the scale. The scale itself is curved. There are fewer reference points at the top than there are at the bottom (for mechanical reasons, however, who needs max resolution at WOT? The EEC has reverted to that table way before you got the throttle fully opened).
