Hi Brian. I am doing another layer of analysis on the 2025 Boston cutoff time that I hope to finish soon and if there is any useful information there I will publish it. You mentioned that you had difficulty getting the Berlin Marathon data but I figured out how to get that although I only care about possible BQ's so I only extracted up to 4:50 for men and 5:20 for women. You are welcome to that data if you think it will improve your analysis - I can send you a csv file. Let me know. (PS I haven't completely internalized your latest post but will when I get a chance.) -Joe Drake
