Don't know what type of experiment you're recording, but since your
example included values to 2 decimal places, I'd think it could easily
be the case that 1,00 is just as likely as 1,01 or 0,99 or any other
value.

I don't understand...
my data values (let's call them "output") refer to a parameter related to
the behaviour of an element subjected to increasing load; they could be
considered as the "level" of stress inducted on the element. When "output"=1
my element becomes unstable...but I can still increase load until
"output"=10. For this reason, I want to know at which step output=1, or
better, when "output" passes through 0,... to 1,...
