Recap
Cold Weather Tax: 36 yards off your summer number
Your typical 8-iron carry is 150 yards in summer conditions with no wind. Today you averaged 114 carry in 58-degree temps with a 10-12 mph headwind. That's a 36-yard gap. Cold air is denser (more drag), the ball doesn't compress as well off the face, and a headwind compounds both effects. Your ball speed averaged 100 mph here vs 103 mph from the March 21 session in milder conditions. The 3 mph drop alone accounts for roughly 8-10 yards of lost carry. The rest is wind and air density. This is normal early-season stuff -- don't chase distance, just note the adjustment.
Warmup Arc: Two different sessions in one
Shots 1-8 were a warmup. Average ball speed was 98 mph, average carry was 105 yards, and your notes reflect it: 'leaked right,' 'slice,' 'skull.' Shot 8 was the low point -- a skull that traveled 22 yards flat and 76 total. Shots 9-17 were a different player: 102 mph average ball speed, 122 yard average carry, and your notes shift to 'best contact so far,' 'well struck,' 'ideal shot shape.' The speed delta is +4 mph, the carry delta is +17 yards. You needed about 8 shots to get loose. That's worth knowing for course warmup routines.
The Right Curve Is Your Stock Shape
Every single shot curves right, averaging R15 yards. Even your best-struck shots (12, 13, 16) curve R12-R21. This isn't a problem to fix -- it's your shot shape. The issue is the spread: curve ranges from R2 (the skull) to R24 (shot 5, a slice). Your good swings produce R7-R16 of curve. When it creeps past R20, the face is too open at impact and those shots land short and right. The curve number is your canary in the coal mine.
Left Start, Right Curve = Your Best Shots
Your best shots (12, 13, 16) all start left of target and fade back. Shot 12: started left, faded R16, landed L4 offline. Shot 16: started left, faded R12, landed L19 (a pull-fade that over-drew the start line). When the start line goes left AND the fade brings it back, you get your desired shape. When the start line goes left but the fade doesn't come back enough, you get a pull (shots 14, 17). When you start straight or right and fade, you get a push-fade that ends up R11-R16 offline (shots 4, 5, 6). The recipe is clear: start it left, trust the fade.
Shot 14: The Mystery Rocket
Your notes said '124 carry, 104 mph ball speed' but Toptracer measured 130 carry, 107 mph -- your fastest ball speed of the session. But the launch profile is totally different from every other shot: 10-degree launch (vs 20-degree average), 13-yard height (vs 26-yard average), 32-degree landing angle, 4.5s hang time. This was a low punch that ran 11 yards (130 carry, 141 total). It also pulled hard left (L15 offline). You probably delofted by trapping the ball with a forward press or a steeper angle of attack. Pure contact, wrong trajectory for a stock 8-iron.
Distance Control: Tight when contact is clean
Excluding the skull (shot 8) and thin (shot 10), your carry ranges from 112-130 yards -- an 18-yard spread. That's still wider than ideal but much better than the 108-yard range including outliers. Ball speed on clean strikes is 99-107 mph. The shots that felt best to you (12, 13, 16) clustered in a tight 124-127 yard carry window with 102-105 mph ball speed. That 124-127 range is your cold-weather, headwind 8-iron number. On the course in these conditions, plan for 125 not 150.
Stopping Power: Steep enough to hold
Average landing angle is 48 degrees -- well above the 45-degree threshold for holding greens. Average rollout is only 4 yards (114 carry, 118 total). Your ball is coming down steep enough to stop, even in windy conditions. This is consistent with the March 21 session. The only shot with significant rollout was #14 (the low punch) at 11 yards. When you make normal contact, the ball checks.
Comparison to March 21 Session
March 21 (68 degrees, 5 mph wind): 142 carry, 146 total, 103 mph, 33 shots. March 24 (58 degrees, 11 mph headwind): 114 carry, 118 total, 100 mph, 17 shots. The 28-yard carry drop is mostly environmental. Ball speed only dropped 3 mph, which means your swing speed is consistent session to session. The bigger factor is the wind and cold air. Your curve increased slightly (R15 vs R13 from March 21), which could be the headwind exaggerating the fade. Consistency score went from 39% to 59%, but that's partly because the March 21 session had 33 shots and more variance.
Next Session Priorities
1. Keep the warmup to half-swings and easy tempo for 5-6 balls, then shift to focused shots. You needed 8 shots today to find it -- shorten that.
2. Your stock number in cold/wind is 125 carry. Use that for club selection until the weather warms up. Don't force summer distances.
3. Watch the curve number. R7-R16 is your good window. Past R20, you're losing the face.
4. Start the ball left and trust the fade. That's your best pattern. The pull is a better miss than the push-fade.
5. Shot 14 showed you can generate 107 mph ball speed. The speed is there -- the consistency of contact is the variable to work on.
