1. The lap speed is calculated from the time of the lap. Some of the older laps were not timed with the same accuracy as now and so there are a small number of discrepancies from the "official" record in the decimal places of some of the older speeds.
2. The list that Silja has linked to has not included some laps that were then subsequently beaten on the same lap by another rider. In 2016 Ian Hutchinson beat McGuinness's 2015 record on lap 1 of the superbike race, starting from position 4. Michael Dunlop beat his lap time by 4 seconds on the same lap, but starting from position 6 meant that Hutchinson held the record for approximately 16 seconds. Similarly in last year's Senior Dean Harrison beat the outright lap record on lap 6, but was himself then beaten by Hickman's 135mph lap less than a minute later.
3. I don't have the raw data for years earlier than 2009 to know if there are any other instances like the two I mentioned in point 2, nor to confirm which lap number the record was set on.
To (almost) complete the list with the lap number the record was set on:
