Generally the requirements for a reverse bid is 17 hcp. This hand although it is close should be perhaps devalued by a point with QJ holding bringing it's value to 15 imho. When I am faced with the decision of which way I will stretch the truth I go low. My thinking on this is if my pard cannot find a second bid I am probably going to get a good result playing a tad conservative.
Don't punish yourself for making an agressive bid Gipp as it means you are thinking about it.
