Most Russian coach's can't teach axel technique well other than Mishin and Volchkova. Look at Tutberidze's students such as Julia and Medvedeva, neither have great 2A technique. You need to stop picking on Goncharenko because her students are a threat to your favourites.
I agree that sky_fly20 is picking on Goncharenko, but I don't think anyone takes sky_fly20 seriously, after sky_fly20's frequently picking on skaters' size and weight.
I disagree that most Russian coaches can't teach axel technique well. The posters are complaining that the 2A of many Russian skaters is too low , but that's the technique you use when you are planning to add 3T after the 2A. And most Russians skaters use this combination. If you do high or huge 2A, it is much harder to add the 3T because you need much more control on the landing of the 2A. Take notice Mao Asada at worlds this year. She landed beautiful 3A in her FS, but when she was supposed to do 2A-3T she messed up the 2A and the 3T did not happen. The same with Gracie Gold in the FS - planned 2A-3T, but the 3T did not happen. If 2A is huge, it is VERY hard to add 3T. I am not saying impossible, but far too risky. If the 2A is low, as long as it is fully rotated, it is counted, so why make it huge and risk the success of the combination?
