Single Engine versus Multi Engine Helicopter(safety)

OK Its the old chesnut reborn. Last week I overheard a pilot waxing lyrical to some VIP passengers that Multi engine helicopters only had a 2% safety improvement over Single engine helicopters!! so for the extra cost the Multi engine was just a waste of another US$1.5 million

I would love to know the figures upon which this was based.
Are they comparing like with like?? only types I could think of would be AS350 v AS355 or A109 power v A119 Koala.

I fly both multi and single machines and I always feel happier in the twin, not just because of the extra donkey, but also the extra generator, hydraulic system Etc. Am I wrong to feel "safer" in the twin. what are the figures on this??

Please don't post the usual "well they still share the transmission/tail rotor/fuel source". that does not really prove one type over another rather its an event which is equally likely in either!!
just deal with the differences and statistics to support/refute multi engine safety advantage .

Thanks
