Well said and a good scenario given. However, i quote from your message *(I do not think they reject for anything)* Trust me buddy they do, there`s been a lot of rejection cases from rounding up years, some with just 3 days apart, some with just a week apart, some with couple months apart. I would not want to see a fellow human being make the same mistake that could have been easily avoided.Guys that depend (I do not think they reject for anything) it depend if you are applying out side or inside Canada, the system have some bugs there are many situations and cases that i listened:
For example: Imagine that you have 9 years working full time for the same company in your country.....you coming to Canada to accompany your wife to study. So you have to give up your resignation before move to Canada respect the job in your country.....after you arrive Canada then....you Start working in Canada and apply while in Canada for the MPNP. For this case automatically when you put the dates example: (9 year experience time in your country 2007/07/07 to 2016/06/23) (6+ month experience time in Canada 2016/07/23 to 2017/01/23) in the system although the reality you have more than 5 consecutive years fulltime the system goes crazy and tells you that you have less which is not true. For these cases as long as you have the work letters and the proof of the 9 consecutive year there is no problem. Perhaps you have the experience that is required, and you are telling the truth but the system calculates it otherwise.
I put these cases because they always help to understand. it all depends your case.
Thanks
