It's all good Tony, nobody is saying it was you. Like I have said above, it can be annoying but it isn't a problem ( apart from their aircraft not being able to make the runway if they have a engine failure which would be embarrassing). I have seen this happen over the years and generally as low hour pilots get more experience, they will generally tighten up their circuits. Being a old ultralight pilot, we were taught to keep real close to the runway from day dot.
