Something went wrong with these results. I may have made a mistake in the suggested timing. I'm not sure what to do.
Is the REW acoustic timing working correctly for you? The expected SPL support did not occur and the timing appears much closer, but is still different than expected.
Has your older thread setup changed? I either need to look back and read through the old thread to recall the equipment and background of your setup, or maybe you can summarize it again. I just opened one old mdat there at random and the SWs impulse trace looked much more conventional. This SW impulse measurement suggested possibly multiple SWs with a with significant divergent timing. Because of the very smooth SPL result and wide overlap in the XO range, I went ahead and provided a timing that should have worked well for SPL.
I could just redo the timing again using this latest mdat if you think they are good measurements. Please advise.
