  "abstract": "Moisture preparation, moisture at testing, and timber variability can jointly influence the response of metal-plate-connected (MPC) members. This exploratory re-analysis concerns 18 C24 Norway spruce assemblies (45 × 170 mm) with Mitek T150 or Ristek LL13 plates. The principal comparison includes 14 directly conditioned specimens in nominal 15%, 20%, and 40% preparation groups, with only two or three beams per connector–group cell; four moisture-transition specimens are described separately. Pooled mean ultimate loads were 14.15, 11.41, and 10.22 kN, respectively. An additive model summarized a nominal-group association (F(2,10) ≈ 12.29, p ≈ 0.002; bias-reduced, nonpartial ω2 ≈ 0.587), but this estimate remains uncertain in such a small sample. The connector comparison was inconclusive (p ≈ 0.122), rather than evidence of equivalent performance. In the nominal 40% group, reported mean moisture differed substantially between Mitek and Ristek (40.45% and 26.35%), and resistance-meter readings in the wet range lack documented validation. Separate verified moisture records at pressing and testing, and the timber-allocation procedure, are not documented. Consequently, preparation history, test-state moisture, connector system, and possible timber-batch differences cannot be separated causally. Laboratory coupons were summarized at the parent-beam level, without treating subsamples as independent treatment replicates. The findings identify associations requiring a balanced, replicated experiment; they do not establish an assembly-moisture effect, a connector ranking, or a design reduction factor.",
