That is correct.
Today I measured the post boil gravity before chilling the wort by cooling down a sample in a large stainless steel bowl and then using a hydrometer. The gravity I measured doesn't match the gravity I got when I measured the same wort after chilling with an immersion chiller.
post boil and pre chilling ~ 16.0 Plato or 1.064
post boil and post chilling ~ 17.0 Plato or 1.068.
That is to large to be caused by looking at the hydrometer in different ways. I even compared both samples at the same temperature.
What's going on here? Is it the precipitation of cold break. But 1 Plato difference is a lot. That is 1% of the weight of the wort. No water was added by a possibly leaking immersion chiller as the volumes pre and post chilling matched once corrected for temperature
