Sorry for long delay with answer .
There are no letters in ivann-slavinskiy at rambler dot ru 🙁
About TFO testing: yes, I don’t like results too :)Looking through total benchmarking reports everything seemed all right. But analyzing deeper through the logs and obtained results I’ve already found lots of mismatches. I need some time to find out the truth 🙂
About non-homogeneous calls – of course they can’t 🙂
About interference – it’s more than possible because drive-test was made in town with very high traffic and high index of frequency reusing (the next object for optimization for our group 🙂
