Not a bad video.
But the major flaw is defining only 3 types of spin
It has to be classified as 4 types spin
No spin ( or flat hitting ) play style or block & smash style has been part and parcel of the table tennis tennis mainstream till 80's .
The ITTF's maniacal obsession to turn this sport into singular homogeneous top spin only Olympic table tennis has destroyed no spin & back spin styles of play , lot more so on men's side than women
Zhuang Zedong & Jiang Jialiang were great many time World Singles Champions from no spin style
Not to forget Johnny Huang . He Zhiwen & Matt Falck
There were women World champions as well

Tennis more or less went the same way. Jimmy Connors was probably last true flat hitter
There is a lot more to this story of all spins table tennis which sort of relates to Connors (& Borg etc.)

If one needs to appreciate how difficult a sport table tennis is, all one needs to do is too look at the lowest rating events in this tournament

They have an Rating Under 150 event

(I believe USATT set the lower rating limit at 200 but this will probably be update later , that is fine)
