Where the estimate matched a measurement, and where it has not been measured

3 in-house calibrations are listed on this page. The compared rows are Qwen2.5-3B-Instruct on GeForce RTX 4090 24GB (desktop). Predicted total bytes are compared with measured process GPU bytes, not with board-used bytes. These rows stay separate and are not rolled into one error figure. Planned, with no measured bytes: Qwen2.5-7B-Instruct, Qwen2.5-32B-Instruct, and NVIDIA DGX Spark (GB10, 128 GB unified).
