If I use the same barbell when I bench it doesn't matter how I record the weight as long as I do it consistently. You use as much weight as it takes to hit 8-12 reps to failure, record that amount and then next workout either you get more reps or use more weight. It would only make a difference if one day a 45 lb barbell wasn't available and I had to use one that weighs different. What's important is to monitor your progress consistently, either include the weight of the bar 225 or exclude the bar 185. The only time this wouldn't be the case is if you are either a competitive powerlifter, or bragging to your friends on how much you bench. If that's the case then you wouldn't be using the machine. The target weight is in your head, the point is to stimulate the muscle to grow. Now if you aren't able to use the same machine one day, or are trying to translate this into how much you can benchpress you have other factors to consider besides weight, ie. the action of the machine, angles, leverage, etc.
