Why do people use large potential ranges in Tafel polarization experiments?

At the conference that I visited some days ago, there were many (more than a dozen) presentations, in which people measured Tafel slopes in for a very large range of potentials. let's say, 0.5-1.0 V cathodically and 1.5-2.5 V anodically relatively to the corrosion potential. Particularly often these very broad potential ranges were used for the Ti / H2O corrosion system.

For me that was quite a surprise, because I know that:

 (1) the working electrode is severely damaged (or, if put it more mildly, CHANGED) by potentials so far from the steady state, especially in the anodic direction;

(2) Most standards (ASTM and others) recommend the potential range of +/-0.25V or even +/-0.16V relatively to the corrosion potential.

I have asked questions about this at the conference, but have never heard a satisfactory answer. It would be odd enough  if many good men and women all made the same mistake in the experiment setup; and I therefore suspect that I do not know something important about this. Therefore I would really appreciate the comments of the highly esteemed community.
