-Transition was a tad too high but you have the right idea! So we have the airport elevation at 2872 feet which rounds up to 2900 feet. We have to add 1500 feet to that to get the highest altitude someone will be in the pattern at and add 1000 feet to that to have minimum separation with the pattern altitude and aircraft doing the transition. That comes out to be 5400ft. We round that up always to the nearest 500 so your transition would be 5500. This trips up a lot of trainees so if you have any follow up questions let me know! And FYI you always round UP. You never round down to the nearest 500.
-On upwind when I requested a runway change with traffic right next to me on the runway to the right of me you should of given me an extend upwind command. I remain runway heading while the traffic just right of me turns for crosswind. When I have enough space to enter the right pattern for 28R you can tell me to turn crosswind and give me a pattern entry without any conflict in upwind since you are controlling when I make my turn to enter the right pattern.
Overall a very solid session indeed! Keep it up.
