I meant to compare mainly from a user perspective. If a train runs every 4 mins and takes a bit more than an hour to get to it's destination that's very similar to the tube experience. Very different to a typical train experience where you have to turn up exactly in time or wait another 30 mins for the next train. The point I was trying to make was that a comparison to HS1 without accounting for the train frequency is probably not fair.
