I agree with all of this, except I probably wouldn't call follow or draw "English" (but that's a minor semantic concern).

Quote:
…the 5 types of English are as follows:

1. Draw
2. Follow
3. Inside
4. Outside
5. Passing

……Draw is the reversing of the natural rotation on its horizontal axis…..of the CB….before and after contact with the OB……the range varies from…slowing down to actually reversing the forward motion of the CB…..

……Follow is the exaggeration of the natural rotation on its horizontal axis …..of the CB……after contact with the OB…..
I'd say "Draw is any reverse rotation remaining on the CB after contact, causing it change direction toward the shooter." and "Follow is any forward rotation remaining on the CB after contact, causing it to change direction away from the shooter."

Quote:
……Inside is the imparting of a spin on the Vertical axis…of the CB…which is derived by striking the CB on the side……away from the cut angle of the shot itself….. and forcing the gear action of Friction to throw the OB onto a caused trajectory….toward the cut angle….
I'd say "Inside spin is horizontal spin (around the vertical axis) used with a cut shot, caused by striking the cue ball on the same side as the direction (left or right) that the OB will go. Inside spin causes the CB's surface to rub across the OB's surface in the direction of CB travel, causing friction that tends to "throw" the OB slightly off the line of CB/OB centers (the cut angle) in the direction of CB travel."

The reason I'd say "tends to throw the OB" is because if there's too much rubbing speed from the combined collision speed and sidespin speed, then there's less throw.

….Outside is the imparting of a spin on the Vertical axis….of the CB… which is derived by striking the CB on the side....toward the cut angle of the shot itself…..and forcing the gear action of Friction to throw the OB onto a caused trajectory….away from the cut angle….
I'd say "Outside spin is horizontal spin (around the vertical axis) used with a cut shot, caused by striking the cue ball on the opposite side as the direction (left or right) that the OB will go. Outside spin causes the CB's surface to "roll" across the OB's surface, reducing the rubbing speed caused by the collision of the balls. This may reduce or increase the rubbing friction between the balls (depending on the resulting net rubbing speed), reducing or increasing "collision induced throw".

Quote:
…….Passing is the natural gear action of Friction toward the cut angle……transferred to the OB by the forward and angular (to the OB) travel of the CB …..when it impacts the OB…..without the assistance of side English……(draw will exaggerate this and follow will decrease it)
I'd say "On cut shots the CB strikes the OB at an angle so that the CB's surface rubs across the OB's surface in the direction of CB travel, causing friction that tends to "throw" the OB slightly off the line of CB/OB centers in the direction of CB travel."

Quote:
......(imo) "the decision to use....side spin ...and which (inside or outside) to use......should be qualified by considering the following"....

…...is my primary reason for using side spin,

1. to increase throw of the OB already directed by the passing English ?....

2. to counteract the passing English ...and alter the trajectory of the OB ?....

3. to control the path of the CB ?...

4. a combination of the above ?.....
I'd add that the decision should also include a "risk/reward" analysis: Does the spin make this shot harder than the next one would be if I didn't use spin?

Quote:
...#1 uses inside English to impart a of change of OB trajectory toward the cut angle of the shot....
I'd say "...a slight change of OB direction in the direction of CB travel."

Quote:
...#2 uses outside English to negate the passing English and alter the natural trajectory of the OB away from the cut angle of the shot…..
I'd say "...to reduce the rubbing speed of the CB/OB surfaces, which may reduce or increase the rubbing friction between the balls (depending on the resulting net rubbing speed), reducing or increasing "collision induced throw".

Quote:
…..#3 uses English to control the trajectory of the CB after contact with an OB or a rail….(unless a Masse’ is produced whereby the trajectory of the CB changes before contact with the OB...and inside English allowing the contact point to be beyond the line of sight (the Bowling ball affect))
Just a comment: masse can also change the CB's direction after contact with the OB. Here's a video by Mike Page about that:

Quote:
……#4 is like multi tasking…..controlling the trajectory of the OB…and at the same time the trajectory of the CB….before and or after contact with the OB (much more difficult).....


.......You can see how that affects your decision to use...the side spin....by polling your use during play......after you use the side spin....think back and see.........what was the.....the primary reason for the use.......of the side spin ?.....

....(imo) I think You'll find that the primary reason...is to control...the CB......and the throw on the OB is secondary.....

.......that being said.....the throw of the OB...is an essential part of any shot...and needs to be addressed....to achieve the correct contact point on the OB to pocket or position it….

......now because my definition is an ongoing evolutionary process....I humbly and readily accept any and all....corrections or contributions to it......
You asked for it!

Hope you'll take my comments in the spirit they're intended: not to critique, but to share info that may be helpful and clarify both of our comments.
