Let us assume a 2/1 SWR and a line loss of 10% (Makes math easy)

Transmitter out 100watts
Power delivrd to antenna 90 watts
Power returned 81 watts
Power re-reflcteback to theantenna (Very good tuner) 80 watts
power delivered to antenna 2nd time72 watts
Power reflectd 36 We have now radiated 86 watts

As you can see every time we make the trip we loose line loss. TWICE.

My tuner is o.00 inches or mM from the antenna.. Thus the line loss between tuner and antenna is 0.00 watts.. All my losss are in the wire (Antenna) and tuner... This is because the tuner is the antenna feed point. Long wire antenna. End fed.
