Just to give a dawdler's perspective:
I stop over on the way to Europe, preferably in Singapore. There, to keep it simple, I can sleep at the airport hotel without doing customs and immigration. Chicken-rice time! If I take that combo where you leave Singapore within 24h, my luggage is automatically booked through to Paris. On arriving in Paris, I just head for the Bastille-Marais area and spend a night there. (That's the part of Paris I prefer to the big monumental end. It's fun.) Then I dawdle on to Le Puy by train, as described. Maybe I'll stop in Lyon some time, just to check it out.
I spend plenty of time in Le Puy, then, when it feels right, I start walking up the Aubrac Plateau. (Although next time it will be the Stevenson or Regordane.)
When the money and/or Schengen period run low, I head home from wherever I happen to be, with much dawdling and stopping over, so I don't have to endure long train or bus rides. (My post Camino stops have been San Seb, Bordeaux and Segovia. Choice!)
To plan my trips and Caminos, I ask myself one brutal question: What would a real sissy do?
