With a sample size of just 3 titanium frames, the margin of error is kind of big.
If the actual Ti failure rate is 10%, the chance of getting at least 1 failure is:
1 - (0.9 * 0.9 * 0.9) = 27%
Statistics rambling aside, point taken about the way the material is used being the most important factor.
