No, the problem is that TIGER uses privacy-obfuscated potential
addresses, while the Karlsruhe Schema is set up for actual addresses.

Yes, in some locations the error is small - in particular if the
potential address range and the actual address range are similar.  In
other locations the error is much larger.

TIGER is fine if you don't have anything else.  But that's not the
case where I live.  It's fine to fall back on if your actual address
search fails.  But adding it in a way that encourages people to
*update* the potential addresses with actual addresses defeats that
possibility.
