Hi,
Looking at a 2010 diesel SUV with under 80,000km. Good service history. The seller has supplied a report which indicates compression in the 4 cylinders at 100% 94% 100% 98%. Would this be considered normal or suggest an issue.
Thanks in advance for your opinion.

The cylinder compression is not measured in percentage so I would presume this is a relative compression test result.

Relative compression tests are widely used these days as it doesn't require the dismantling of any parts and instead it's an electronic measurement of the effort the starter motor uses to turn over the cylinders.

The relative compression test results you have supplied are acceptable.
