Second in a three part series looking at the differences in performance between 2.2 and 2mm table tennis sponge thickness - using Giant Dragon Maxspin.
In this video we test to see if there are differences in terms of:
1. Maximum throw height
2. Trajectory - high arc or shallow
3. Speed
Using high speed footage we also look at why one of these sponge thicknesses is possibly slower and has a steeper throw arc and show the ball "visibly climbing up the top sheet surface".
We also identify problems with testing and comparing rubbers and why it's important not to look at just one factor, such as sponge thickness, when considering how or why a table tennis rubber performs as it does. In particular we look at tackiness, sponge hardness and thickness and show how different combinations of these factors can have significantly different results.
Other videos in this three part series are:
1. Physical properites including dome, curl, weight, top sheet, tacky test, grip test, cutting on a bubble in the top sheet and other possible quality control issues
and
3. Human testing - demonstrates how different people can rate the same rubbers performance.differently in terms of serving, returing serve, pushing, top spin driving, blocking, power loop, brush loop, smash, chopping and questions the relevance of generic speed, spin control ratings.
These videos will be released staggered. Part 3 to be released some time next week.
