Ah leady, picking on small typos in late night forum posts and clapping your own wisdom, the sign of a true intellectual.
I do not make money from doing aircraft maintenance, I used to but have moved on to other pursuits where less people share unfounded opinions on how I should do my job. When I did do maintenace I appreciated those owners with a 6 point monitoring system on which I could base my informed decisions. However since this accounted for about 50% of the aircraft I maintained I was forced to work with the tools available - a compression guage, master orifice and borescope (correct spelling by the way - boroscope is an americanism). If you have a way of verifying the condition of cylinders without 6 point egt/cht or these tools let me know.
Jaba will be happy to verify my engine maintenace credentials and my role in reducing cost to aircraft owners.
