Just be aware that there is absolutely NO visible difference in image quality between saving the JPEG file at 80% (PS Level 10) and 100% (PS level 12). There is a small measurable difference between an 8 bit TIFF file, and both the 100% and 80% JPEG files, as well as between the two JPEG files. So although you can measure a slight difference between 80% and 100% JPEG files, the measured difference between the two qualities of JPEG file, and an uncompressed 8 bit TIFF file are of the same SIZE. As a Q80 JPEG file is between 60% and 40% smaller than the Q100 file size, this makes a significant saving of disk space, with no appreciable loss of image quality. You actually have to reduce the quality setting down to around Q60 in LR (PS Level 8) before you actually start to be able to discern the effects of JPEG compression.
Although LR has a scale from 0-100 there are actually only 13 levels of compression available, corresponding to the Photoshop range of 0-12.
Using JPEG at Q100 is really pointless on a file size basis too, I have seen JPEG compressed image files saved at Q100 that were larger on the disk than the 8 bit uncompressed TIFF file they were created from. Also you can apply lossless compression to a TIFF file that will reduce it in size significantly, without affecting the image quality at all, if you are really after maximum image quality.
