I have no reason to believe the decompression algorithm run by the Eon Steel is any different than the Suunto RGBM algorithm run by other Suunto computers. This is supported by the owner's manual. Of course you can change the personal conservative factor to -2, who knows exactly what that does as the algorithm is proprietary and not included in any dive planning software other than Suunto.
I thought the documentation said the Steel runs "Fusion RGBM", where other Suuntos run other variations of RGBM.
