Just a quick note about pips.
There are about 17 or
pip design parameters
But the primary parameters that differentiate the two primary pip types
is NOT the length , when ITTF banned long pips in 1977 at the Birmingham BGM , they set the maximum allowed pip length for any & all pips at 2.00 mm. This limit was changed at the 2024 AGM in Busan, South Korea, to 2.05 mm for political reasons , that I will not get into here.
So what separates the two major types of pips . It
is NOT the pip length . It
is the pip width , because the maximum allowed aspect ratio for one type of pips
is set at 0.89 and other pips between 0.89 & 1.1 .
What does that mean ? This means that for one type pips the pip width cannot exceed 2.05 mm divided by 0.89 , which gives 2.3 mm. These are the wide (stiff) pips .
The other type of pips are the slim (flex) pips whose maximum allowed pip width
is 2.05 mm divided by 1.1 which
is 1.86 mm. So these are the slim (flex) pips.
Another primary distinguishing parameter of the pips was the pips stiffness or flexibility. Traditionally , the wide pips were stiffer and slightly shorter (that
is why they were called short pips) & slim (flex) pips were flexible and at maximum length. But of late manufacturers have been making wide (stiff) pips also at close to maximum allowed length of 2.05 mm but also flexible (but calling them wide pips) to confuse the clueless and sell these rubbers as chopping short pips LOL
Anyway going forward please identify the "short" pips listed as "out" on ITTF LARC as wide (stiff) pips & the other pips listed deceptively as "long" on ITTF LAR as slim (flex) pips to avoid confusion.
And refer to the actual "long" pips with pip length higher than 2.05 mm and aspect ratio higher than 1.1 as long (flex) pips.
Keep also in mind that ITTF reduced the maximum allowed aspect ratio of pips from 1.3 to 1.1 at the Durban 1998 EGM
This
is the most infamous, most political & most oppressive rule or regulation change in the 100 year history of the sport.
