^^^ This is where my limit of US coaching systems starts to fail! I'm a USPTA Pro 1 level, but by association. The PTR over here was regarded as a bit mickey mouse, but I believe the franchise is now run by a different team and I'm have no recent record to go on. Might need some others with a better working knowledge of how things work over there to chime in!
RPT certs are hard to find as they would either have to have qualified in Spain, the UK or gone to Naples to take one of the A-SC Florida courses. Probably not that many relatively speaking.
I may be average... but my average is still ****ing awesome
