Generally, there shouldn't be more than a 15% difference between the highest and lowest cylinders- 10% is better. I would look for at least 160-170, on average. This needs to be done at normal operating temperature, no spark plugs and no fuel, so the fuse for the fuel pump or injectors should be removed before starting.

Can you not just pull the safety lanyard off?
