Hello, noticed this issue by chance. In [my experiments](https://github.com/PavelVesely/SplineSketch-experiments) with [the original implementation](https://github.com/tdunning/t-digest), t-digest is actually pretty bad in keeping the number of centroids close to the prescribed size. (Specifically, I have to [manually adjust the number of centroids](https://github.com/PavelVesely/SplineSketch-experiments/blob/320019fe9d156a42ec6c1edba880d060de8a1b13/run_sketches_fncs.py#L62). Btw, the experimental results are in [my recent paper](https://arxiv.org/abs/2504.01206).) So I believe it's the property of the exact implementation of the algorithm (perhaps some adjustments of the algorithm could fix it but could also make the accuracy worse). -- This is an automated message from the Apache Git Service.
