“Melco SUMMIT runs at up to 1,500 stitches per minute, "one of the fastest stitching commercial embroidery machines available"”

1,500 stitches per minute is stated directly by Melco's own SUMMIT product page, both in the feature list ("Up to 1500 Stitches Per Minute") and in the "Peak Performance" section, which also carries the exact superlative quoted in the claim. Source 2 (Tajima TMBP2-SC) does not contradict this: it lists a maximum speed of 1,200 rpm for a different manufacturer's machine, which is consistent with Melco's relative claim rather than opposed to it. Note that the superlative is vendor marketing copy from Melco itself, not an independent benchmark, so it is confirmed as an attributed quote rather than as a verified industry ranking.
