On the way home today I realised how my comments could be taken to mean I believed the aikido I was studying was 'pure'. This was a miscommunication my end.
What I was trying to convey is that my aikido is definitely not pure Yoshinkan aikido, and it is this that leads me to my current challenge, where my rank is awarded from Yoshinkan Honbu, and my students are following the Yoshinkan syllabus, yet my training and experience is not only Yoshinkan.
I hope this is clearer and I have not muddied the water further!
with best regards,
