discrepancy in results between illuminance and annual daylight components

Dear all,

I've been trying to compare and see how accurate is the hourly illuminance values yielded by illuminance component (tried all sky types) to those by annual daylight component in a simple room, and I always find that there's a small difference of around 800 lux between the two components, although both of them should have the same results unless I'm doing something wrong, and I don't know what is going on wrong. I tried this with high quality ab, so it should be quite accurate.

please find attached GH file. could you please advise on what could be wrong?

Thank you for your help.

Mina
