Yes, absolutely.

Yes, Matthäus' technique certainly has some advantages.  But I'm glad we
didn't just do the same thing.  First, he would accuse us of stealing his
good idea.  Second, IMHO any time you try to do measurements like this
you'll find flaws and inaccuracies.  So I look forward to comparing our
results to his and finding where they agree and where they differ.
