Do you mean you can play one set of three keys by day or 3 sets of 3 keys? In the first case, you cannot complete a R&D. In the second case, it's possible but you have to avoid mistakes.

Depending on my work, I can play 4 to 5 sets of keys. It's sufficent as every lab is over with one day less than provided. 911 GT3 RS revival excepted because this R&D was shortened by 2 days and keys were given every 4,5 hours instead of 3.
