Further to my observation on the details & timing in raising GPC & TCM, I have concern and I have revisited our guideline on this process. I found that it is very good document to share with you – you should have seen that before. I have modified the file and added page 15 covering the common confusions among yourselves. Please read through it again and follow them (GPC – use moderate only, TCM - IR scan, moderate of above, etc.). Note: There was a video on page 12 for a quick/useful lesson.Should you have any queries on this, please let Gaby Kun or me know.
