Hi :P

Since there's very few things posted on the SRC LN forum, I decided to make a few threds with some of my findings. Here are a couple of versions of Grinder skip that I found, with a few explanations:

1 - Going around the table and climbing on the left side:

2 - Climbing on the right side of the table:

• go inside the vent, and place the charcter with the back barely visible on the right of the wall;
• hold 'crouch' and 'sprint', and start to walk left when the chef takes his first step forward;
• release 'crouch', and run by the chef when he's about to push the button;
• jump on the right side of the table, and jump towards the key (without picking it up);
• stay on the left of the key (so the chef can't reach you);
• pick up the key after the chef failed to grab you, and walk off the table on the left side;
• sprint around the table on the opposite side where the chef starts to chase you;
• go under the side table and continue to run to the elevator when the chef stops to reach under.

NOTE: the safest way to approach this is to sneak behind the chef and have the chase only at the end, but this proves to be too slow compared to the ones above, that's why I only posted strats with instant chase - when the chef opens the door. (In one of the videos you can see how the sneak version of the skip is much slower - in the comaprion part).
