"Data not decisive" on most stable isotopes

By the time I write this, Tc, Sg, Hs have "data not decisive" footnote beside their mass numbers. However, I found that Lr, Lv, Bh, Ts (and possibly Bk) are all less decisive than Hs. I'm not sure what should I do, either removing the footnote in Hs, or add the footnote to these 4(+1?) elements.

Also, do this footnote need to extend to elements beyond Hs, like all elements with overlapping 2σ confidence intervals? (This adds Mc and Mt to the list.)

@Nucleus hydro elemon: I think 2σ is a good threshold. So yes, feel free to add the footnotes, perhaps with an explanation. :) Double sharp (talk) 14:57, 31 July 2024 (UTC)

Just realized a problem: when we cite NUBASE2020, do we use the symmetrized half-life (using ²⁸⁶Nh as example, 12±5 s) or the original unsymmetrized half-life (9.5+6.3
−2.7 s)?

Nh is a borderline case, if we use the unsymmetrized 9.5+6.3
−2.7 s, then the 2σ confidence interval of ²⁸⁶Nh doesn't overlap with ²⁸⁵Nh; but if 12±5 s was used instead, they crash. Nucleus hydro elemon (talk) 16:01, 31 July 2024 (UTC)

@Nucleus hydro elemon: I would prefer to use the original unsymmetrised half-life. Double sharp (talk) 05:46, 1 August 2024 (UTC)

Added for Lr, but I have struggle on other elements (and Hs too) that don't overlap at 1σ, but overlap at 2σ. I'm not sure if the following:

If the 1σ confidence interval is 9.5+6.3
−2.7, then the 2σ confidence interval should be 9.5+12.6
−5.4

is still in the range of WP:CALC. If it doesn't, I will have no idea on how to write these footnotes. Nucleus hydro elemon (talk) 07:36, 2 August 2024 (UTC)
