a) Thomas tested Rollei Tonal against Acros and
b) Tonal was available back in 2002.
Both is afaik simply wrong and misleading.
(for the non-german readers: Hartmuth Schroeder took a review from Thomas Wollstein of Acros vs. Maco PO100c which he published in 2003 and simply changed PO100c to Tonal. The original review can be read here)
