If the original question was speed through the water then current is irrelevant. (not counting the waves of course) If you just had a knot meter and no way of seeing land, the stars and no GPS, only your hand dragging through the water you would have no idea there even was a current. Now speed across the ground, current would matter but it is still a performance question. Same as a aircraft through the air....
If you always put limit on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.
LET'S GET SERIOUS ABOUT ENFORCING OUR PRESENT LAWS NOW
