room cal workflow question

Hello. Wondering how others handle this: do you calibrate your monitor listening levels for different delivery types? Example: if I cal my space to 79db @ -20dbfs with peak limit at -10dbfs, should I recalibrate when I'm working on a mix for dvd with higher peaks , say -3db?

Re-calibrate according to your intended average dialogue level, not the peaks.
Here's my little re-calibration cheat-sheet:

Dlby = dBSPL = LUFS =
7___= 85____= _____(THEATRICAL)
6.5__= 83.33_=
6___= 81.66_)~ -27__(DVD 27 dialnorm)
5.5__= 80___=
______79____~ -25
5____= 78.33
4.5__= 76.66_~ -23___(TV mix)

First column is the Dolby cinema processor volume pot (which may not be relevant to you.)
Second column is the SPL, measured with a radio-shack meter, slow, C-weighted.
Third is the LUFS level that I feel comfortable about when working at the given calibration.

Please note that this is just my personal cheat-sheet, which may not be appropriate to the others - eg -27 LUFS may sound too loud to somebody at 81.66 dB SPL. Another example is that, contrary to what most people feel like, my mixes translate to the dub stage best when I'm at 85 in my home studio.

Great. Thanks for that.
