Send a correction or a source
The fastest way to change a number on this site is to send the page that shows the right one.
What helps
- A wrong spec or price. The racket, the figure, and a link to the page that shows the correct one.
- A missing racket. The manufacturer's product page.
- A problem with the formula. Which weight or direction, and the evidence.
- Manufacturers. If your published specification is incomplete on your own site, publish it there and send the link. Figures sent privately cannot be used, because readers could not check them.
