has it given the ISP�s a way out of displaying statistics?
As the OP, I feel only fair to answer this.
Far from it. We as an ISP feared and we feel is now already happening is there now appears many different ways for ISPs to present the same exact data (percentages, up to's, regional variations, ADSL v's ADSL2+ v's FTTC) making comparing for the consumer a far harder process.
Our view has always been, when we were consulted, that it's practical to address the concerns raised by the ASA/CAP if the solution introduced was a consistant model across the industry (similar to how energy ratings are found on many goods etc). This way the consumer could compare without all the redtape, as those clever marketing bods could have little room to move.
All we have had this week since we removed data is phone call after phone call with confused pre-sales. We even been asked by we don't listed up to speeds. We now having to flip back to up to in some way as a temp solution :/
