Sorry I misunderstood you the first time... They combined Professional Expense with R&D Expense which incorporated ~16% of Revenue; which is all under the G&A expense umbrella... R&D Expense alone was around $800k while the consultants make up the other $3 million.
This spike should not continue, HOWEVER, I also thought we saw the last of this Consultant payment in Q1 when I thought they had said a "One-time expense". I need to go back in my 10-Q's to reexamine where I read this incorrectly
