Further to the valuable hint to advice, you - like all of us - have been going through three green speeds, standard, fast, very fast, in a confusing hurry. This is history!
"Very fast" will be your standard companion as a TP and as a Master - you will learn it!
I loved it because it has the simplest correction for elevation: One foot of length for one inch of rise/fall.
Another hint of a notorious off-ding putter: Change to "ding" putting - it will be necessary on the faster greens coming up to you.
