All good advice, Loren.
Yuk! I hate having to play on equipment in such foul conditions, however if that is what you must do, and you know it in advance then you have no gripe to make DURING your matches. Keep in mind your opponents are playing under the same conditions. They are probably hating the conditions too. You are at war with them. Don't try to team up with them against the table. The table will win every time. The player who adjusts quickest to the table conditions usually wins, all else being even. Keep your complains to yourself until the nights matches are over and then try to bring your issues to the "powers that be" with a smile, and privately, so as not to embarrass anyone. You might just get better results.
As far as making speed adjustments quickly; If you are sitting in the chair, watch your opponent carefully. Try to visualize the shot your opponent is about to shoot. Check the stroke he or she uses to see how much power they had to gererate to get the cue ball into position for the following shot. Make mental notes and concentrate on what happens on the table you will soon be forced to navigate. Carefully watch to see if a ball comes off a cushion oddly. In other words, play the game in your mind during your opponent's shots. You will find that with a little practice this will help you prepare for when it is your turn to shoot.
