Quarter turn Vs "more than just a quarter"

jim said a long time ago to me that: welding pipe ought to be done with the pipe soft as possible.

and i begin thinking about how pipe is softer in the summer than in winter,

and how friction creates heat.

anyway before I go on too long with all the theorys.

wouldnt a full turn (or perhaps even more) be better "welding" than solely a quarter turn?

I dont think a quarter turn is enough friction to bind the two pieces into one (or atleast is inferior to a full turn, IMHO.

PVC pipe goes together with a chemical bond, the partial turn just spreads the cement.

Page 6 states "Without delay, while the solvent cement is still wet, assemble the pipe and fitting, and twist a 1/4
turn as the pipe is being inserted, if possible. Once the pipe end has reached the fitting socket stop, do
not turn any further; doing so could break any fusion that is starting to occur."
