What is the most throw I can get, and how can I achieve maximum throw?
Maximum throw, under typical conditions, is about 1 inch per foot of OB travel, or 1/2 a ball per diamond on a 9′ table, which is about 5°. Although, more throw can result with cling/skid/kick.
Maximum spin-induced throw (SIT) occurs with slow speed, stun, and about 50% english (for a straight shot). See “Throw – Part V: SIT speed effects” (BD, December, 2006). Per Diagram 1 in the article, below about 25% english, speed has no effect on the amount of SIT! For more information on SIT speed effects, see: HSV B.18 – spin-induced throw speed and english effects.
Maximum cut-induced throw (CIT), with no english, occurs with a slow-speed stun shot at about a 1/2-ball hit. See “Throw – Part II: results” (BD, September, 2006) for more information. At larger cut angles, again the friction is less due to the faster relative sliding motion between the balls during contact. Per Diagram 1 in the CIT article, for cut angles below about 20°, speed has no effect on the amount of CIT! With slow-speed frozen or nearly-frozen combination shots, where the 1st ball will have stun into the 2nd ball, one must be very careful to adjust aim for throw (see frozen ball throw).
