I don't think the thumb on the top grip is considered the most accurate grip. I do think it is considered the strongest grip. If I am not mistaken, for short casts straight line casts, the finger on top grip is considered the cost accurate. Also I believe there is no one grip that is most accurate for all casts at all distances.
Grips differ by the amount of rotation of the hand relative to the rod handle when holding the rod. That is, the thumb on tip grip is more supinated that the index finger on top grip. Conversely the finger on top grip is more pronated that the thumb on top grip.
In some casting motions, as in overhead curve casts, one needs to rotate the rod the rod during the casting stroke. If the stroke requires supination of the hand and wrist during the casting stoke, as a right hand caster making an overhead left curve cast. The cast is easier to make if the grip is a pronated grip because there are more degrees of rod rotation that one can make if the grip "cheats" a bit to the the other side during the start of the cast.
For example, lets say the the wrist can rotate 180 degrees which is the difference between the palm up and palm down position. If we hold our wrist in the karate chop middle position, we can rotate 90 degrees each way. If the casting motion requires us to rotate our hand during the casting stroke to a palm down position (finish the stroke with your palm facing away from you), the index finder on top grip gives you more rotational force because it starts the stroke with the hand in a more palm up position than the tub on top grip.
We cast for distance with our shoulder and forearm muscles, and we get fine motion or accuracy with our wrist, hand and fingers. Of all the fingers in our hand, the thumb is the most important because it gives us an opposable grip. BUT it is not the the one best suited for fine motion. That would be the index finger.
Tape an artists paint brush to your thumb and try painting with your thumb. Now tape the paint brush to your index finger and try painting. Which finger gives you more control? For the great majority of us, it is the index finger. That is the reason I believe the index finger on top grip gives the best accuracy for short straight line casts. It is our natural pointer finger, and accuracy for shore casts is the ability to accurately point the rod at the target.
All grips are not equal, and no single grip is the most accurate in all casting situations; but for short straight line casts, I believe the index finger on top grip for most people is the most naturally accurate grip.
