No it isn't, in crowded conditions I would allow much longer. also
consider many travel with bags having a platform allocated is a great
help in these circumstances.

Thalys is good, even tell you where to stand on the platform, FGW will
not tell you at Paddington which platform the Penzance train leaves
from until 10 minutes before departure even when you can see it parked
there.
