Why would I be disqualified? I don't know enough about established standards to know but I do know the 1-10 min average "rule". Genuinely curious to know and to see whether I can do anything to improve my setup.
I think you don't have to worry, your approach is correct and there is nothing else you need to do.
Some recent positions by WMO, in this field, have generated perplexity on the part of the most advanced amateur community, to the point that many believe that there is a need to review many aspects, both from the technical side and from the purely operational one.
Some continue, insistently not to take into account important aspects that should put us on guard, at all levels, even if you had reference sensors, they are only a miserable part of the problem.
Certification, calibration carried out at an accredited metrological institute, compliance with the times in periodic checks etc. do not give any added value to your measurements, except the recognition of the data, given that we know perfectly well that it is valid even in the absence of such certifications.
The measurement uncertainties, introduced by the installation, and the disturbances that it can generate, have a frighteningly greater impact than a lack of certification of your sensors, proceed as you have done up to now.
This does not mean that, if you are driven by a great passion, you must never lack the will to improve yourself and your data, within the limits that each one must not reasonably exceed.
