One short arrival does not diagnose a slow table. A useful table note connects a repeatable layout and stroke intention to observed contact points, with uncertainty left visible.
Record the baseline
Note the playing dimensions, identified cloth and ball set, date and any recent maintenance. Mark unknown equipment rather than guessing from colour. Use the same balls and positions for comparisons. “Medium stroke” is your own intention, not a calibrated launch speed shared by all players.
Separate observations
First compare a simple roll on the same lane in both directions, repeating rather than treating one attempt as a measurement. Then use a known cushion route and record the first, second and third contacts separately. A change already visible before the first cushion cannot be assigned solely to the third cushion. Your delivery and ball placement remain possible causes.
Avoid the offset trap
Alciatore documents speed, spin and equipment effects, including exceptions to simple long/short rules. There is no justified universal “slow table = add 0.5 diamond” conversion. A local adjustment belongs to its layout, speed and spin. Check it on a nearby layout; if the misses scatter, record that scatter instead of forcing a single correction.
A maintenance boundary
Manufacturer product names are not measured speed grades. Simonis 330 and 760 have different intended ranges; pool cloth is not necessarily napped. Do not infer rubber age or prescribe heating temperature from a missed shot. Ask the operator about persistent irregularity and follow the table manual. The simulator can compare its settings; it cannot sense the room’s humidity or calibrate your physical table automatically.
