Trainlm and Trainbr

I am using for my problem trainlm and trainbr training algorithms for BPNN. I am getting good results but I am confused a little bit about results of trainbr. The results produced by trainbr algorithm are better optimized than trainlm. However I need verification by some expert that either these are ok or there is any problem. The results are shown below.

Input: 32, 30, 34, 35, 36
Target: 0.9900, 0.9500, 1.0300, 1.0500, 1.0700
Trainlm: 0.9934, 0.9523, 1.0279, 1.0536, 1.0665
Trainbr: 0.9901, 0.9501, 1.0299, 1.0501, 1.0699


These results are obtained for validation data. The results in case of trainbr are very close to the target data. However I just want to know that these results are ok or the neural network is not trained properly for trainbr. Advance thanks for any help and guidance.
