I don't recall anyone promising a bullet tram.
We don't have the detailed calculations in hand, but my observations suggest the line has been built with adequate track speed, but considerable impediment at intersections due to the traffic signalling and the need to observe station stops. To date, when I have seen trams testing, they seem to consistently assume fairly lengthy platform stops, simulating a worst-case load/unload scenario. There are certainly hints that the line has been timed cautiously, and it will after all be the TTC operating it.
It's quite likely that the line may operate slowly at first, leading to customer and public pressure to do better. That pressure may be more effective than us transit wonks crying about it ahead of time - the line may have to be a work in progress.
The other part of the issue for me is that there is very little provision for pedestrians crossing over at other than major arteries, ie pedestrian crossings are very far apart. The new Eglinton is far from a walkable street. The temptation to take short cuts is out there. We may not want 80 km/hr line speeds, as nice as that may sound on paper.
