> However, as a father, I also don't want broken duplo pieces, so I wanted to make sure the track is not too much under tension.
The asker severely underestimates the amount of force it takes to break a Duplo piece.

Thus an adult human male (who sleeps, say, 10pm to 6am) is less likely to break a lego brick at 2am than at midnight and more likely than at 4am.
We can also observe this (to a lesser degree) when they build two story Lego statues like at the Mall of America.
I'll admit I've never seen a huge Duplo statue, but I assume the load limits are similar.
A quick but incomplete algo is to ensure an even number of curves and straights. With them even, a bent track needs to be very bent so as to be immediately obvious.
Due to economy of scales, Lego can manufacture those at consistently high quality and relatively reasonable prices. Competition aiming for same quality would be at least similarly priced. Also, its incredibly sturdy. So far I haven't seen a single one crack or break in past 2 years. My kids are not psychos but they for sure have no idea yet about treating their toys with care.
