I think as you do that your riding style may be a contributor to your oil consuption/loss. Any good shop reference will tell you that it is normal for a combustion engine to burn oil. How much?. Well, that can't get any more subjective. If it were my bike and it was performing well I would check the oil level regularly and keep it filled. If it bothered me I'd prolly change the oil and give the container a good once over for signs of metal maybe even pull the front cover and do the same with the sump.
Having had many engines over the years that burned some oil I personally wouldn't worry about it unless I had other signs/issues..
