Oh yes - forgot to mention - with an IMC rating your are also limited to an RVR of 1800m minimum - or the approach plate minima if higher.
Even an IR rated pilot on an SPA must use 800m or the approach plate - whichever is the higher.
And also its illegal to descend below 1000' aal if your minima is not met/exceeded according to ATC/ATIS information.
Hope this helps,
