Thanks for the comments. Regarding re-chunking: I assume the models, the strategies, the dependencies are continuously checken, improved and adapted. I would assume also a re-chunking should be necessary. Not every day of course, but how I can assess the quality of my chunking? Running in parallel benchmarks on two different chunking strategies? Thats means I would need to do double work, creating and using continuously two different chunk systems. Any ideas how to evaluate the quality and performance of my chunking strategy?
