Increasing frequency is the by-far most cost-effective way to decrease perceived travel times...
Yep. And looking at the GJT, I would argue that half hourly service is the absolute minimum before any kind of service splitting can be considered. And that's just on the diminishing returns on the perceived travel time. We're not even looking at the business case for a whole other corridor, to be built to HSR standards for 1 train per hour.
Canadian railfans are a weird breed. We don't even have HFR yet and people are dreaming of split services at frequencies lower than what Renfe, Deutsche Bahn and JR Central would run at. I imagine if I told the Japanese that the Tokaido Shinkansen should skip Nagoya to save 10-15 mins between Tokyo and Osaka, they'd find it pretty funny. And they run those trains every 15-20 mins at peak and every 30 mins off-peak.
