Transatlantic Penalty?

I live in Canada, so one factor I have thought about is the potential impact of being 3000+ miles further from the Betfair servers than the majority of traders (based predominantly in the UK). The Betfair API Refresh Delay displayed within BetTrader Pro indicates there is just a 218 to 234 milliseconds delay in the application requesting an update from the Betfair server and it actually receiving the update. I was pleasantly surprised by that, however that was on a Friday evening Canadian time when few UK Betfair users are active. Today during peak usage, when everyone knows the Betfair site, including the API, is under load, the response figures were still not terrible at between 250 and 300 milliseconds. I can't comment on what the range is for the average user, but given my distance, these figures could be worse. However, while checking out the RacingTraders.tv website today I watched a video by MikeyB and could see that his response figures spend most of the time in the 40 to 70 milliseconds range! Now I think that kind of response rate is an exception to the rule (I could be wrong), and it might not seem like much, but all other things being equal, that could have a big impact when trying to get to the front of the queue (assuming the response time from the API server is a fairly accurate indicator of the time taken for an order I submit to be received by the API server). Not much I can do about it though, but that doesn't mean it should be entirely ignored.

If anyone happens to be reading this and has any info on Betfair API response times within the UK, I'd be grateful if you could post a comment.
