The bootstrap interval included zero for consecutive 0.5 s HFO gap excess in eight SEEG patients. The analysis assumed uniform 30 s gap order and independent, exchangeable patient sampling.

We tested whether short gaps between HFO starts occurred next to other short gaps more often than a fixed reference predicted. We used 16,044 supplied marks of ripples that overlap fast ripples. The public source was OpenNeuro ds003498 version 1.1.1. The study included 136 sleep records from eight patients with depth electrodes. Each reference kept the measured gaps within a 30 s block. Only their order was uniform at random. We counted adjacent gaps of at most 0.5 s. The mean observed count was 0.10227 per channel minute. The mean reference count was 0.10632. Channels, records, source dates, and patients had equal weight at each averaging step. The mean difference was -0.00405. The descriptive 95 percent patient resample interval was -0.01239 to 0.00469. This interval assumes independent, exchangeable patients. Only 445 of 9,980 channel blocks had a variable count under the reference. The primary result did not establish excess gap adjacency or prove its absence. Two secondary checks had positive intervals. These checks do not replace the primary result. The method gives exact count moments and identifies blocks with no order information. All primary blocks passed an independent source-table check. A repeat matched all 39 numerical outputs. Fresh downloads matched all 1,131 source files. The package contains source bytes, hashes, code, results, figures, and repeat instructions. The data are reused from an existing cohort, not an independent replication.
