It's generally .5-.7oz FO ppo. You use less EO (I use about .25oz ppo) and some fragrance oils are amazingly strong, such as lavender (I used .5oz ppo) and some are weak (some I've used 1oz ppo). It also depends on your clients and your own sniffer. Some people light faint fragrance, some like scents strong enough to smack you in the face from across the room.
