The threshold will be even lower, Red Dot 00840 doesn't have the BIG bug.
My Red Dot 02198 has old bugs only, too. In my collection there are another three HP 35 Versions 2 with bugs, but none of them has the BIG bug.

But I received today HP 35 Red Dot with super low and "jubilee" serial number 00100 from a previous owner, a former HP sales manager. This Red Dot has both known bugs and the new BIG bug, too! Not surprisingly the BIG bug appears also as a result of the calculation

10 eex chs 11 ln

But erroneous results give also slightly different calculations such as
