Mr. Simmons. Yes; it could be, if sufficient practice were used. There is some indication of the magnitude of change with one of our shooters who in his second attempt fired three-tenths of a second less time than he did in the first.
Mr. Eisenberg. Mr. Simmons, has data been compiled showing the effect of the time taken between shots on the accuracy of the shots?
Mr. Simmons. There have been experiments run where aiming error has been measured as a function of the time one has to aim.
Mr. Eisenberg. Do those experiments show that aiming error is directly proportionate to the length of time one has to aim?
Mr. Simmons. Not directly proportionate, but aiming error decreases as time increases. But once you get to the area of about 4 seconds in time, then there is very small decrease in aiming error for increase in time.
Mr. Eisenberg. Translating that to this weapon, does that mean that taking more than 8 seconds between three shots should not appreciably affect the degree of accuracy?
Mr. Simmons. The 8 seconds I was referring to is between shots.
Mr. Eisenberg. You said 4 seconds, I thought.
Mr. Simmons. I beg your pardon.
Mr. Eisenberg. And I was saying, if you took 4 seconds between the first and second, and 4 seconds between the second and third, for a total of 8 seconds, on the basis of this data would that mean after 8 seconds you would not be substantially increasing your accuracy by taking more time?
