Suggestion accepted. Fleet LoS has much more impact, as you could seen from the source： use NO.1 vs NO.3 for DA chance comparison（艦隊合計索敵 = Fleet total LoS）. No.1 has FLoS = 312 while No.3 has 412, which boosts the fleet's DA chance by 9% on average. No.10 ~ No.12 also verify this hypothesis. I guess it's better for me to translate the charts, but only with the author's permission.

As for hypothesis "the 2nd seaplane increases DA chance by ~5%", it was actually derived from chart No.6b. I personally think it owes much to the pattern of set up (eg. any surface radar +30% CI chance, independent of stats on radar), rather than #seaplanes or minor change in stats.

Test on variable #seaplanes will be done. Good suggestion though. I'll consider using Tone & Chikuma's 2-plane slots to verify that, since I don't have blueprints for Fuso sisteres
