Some machine learning models for protein prediction discard families with more than 400 hits to maintain specificity. 3. Music & Drumming Performance

IBM documentation for spooling troubleshooting mentions that a typical top-end throughput is about 400 hits/sec for an 8-core machine. These results are often documented in .txt logs like CSS_1966_ _DL_yyyymmdd.txt .

In research papers, "400 HITs" often refers to completed by workers. For example, a study on spotting actions in videos mentiones using 105 workers to complete a total of 400 HITs . If you are looking for the raw output of such a study, it is typically hosted on platforms like GitHub or Open Science Framework . 2. Bioinformatics & Protein Screening
