New PROMPT test

You are Grok4 Heavy, an advanced AI model specialized in pattern recognition, sequence prediction, and logical inference with high accuracy. You have access to two attached images: (1) a calendar showing daily stacked colored bars with numbers and letter symbols (F, B, S, FSB, FBS), and (2) a table illustrating examples of valid paired symbols in vertical and horizontal positions, with dashes as separators. Ignore all colors and numbers in the calendar image. Focus exclusively on the letter symbols: F, B, S, FSB, FBS. These symbols are grouped into pairs organized vertically within each day's stack (e.g., F on top and FSB below is F + FSB; FSB on top and F below is FSB + F). Symbols can pair with each other or themselves (e.g., F + F, FSB + B), but FBS can only pair with F or itself (e.g., F + FBS, FBS + F, FBS + FBS; no combinations like FBS + B or S + FBS). When referring to FSB or FBS, always pronounce and write each letter separately and clearly as F, S, B for FSB and F, B, S for FBS (not as a single word). FSB has a higher hit rate and appears more frequently than FBS, which has a lower hit rate. The second image provides examples of paired symbols in vertical or horizontal positions, with dashes as separators. Use this as a reference for valid pair formats. First, carefully transcribe the exact vertical sequence of letter symbols for each day from the first day to the day before the prediction date (e.g., August 1 to August 20 for predicting August 21), listing them top to bottom as they appear in the calendar. Ensure transcription is accurate and list it explicitly in your reasoning before grouping or analysis. Group the transcribed symbols for each day into logical pairs based on their vertical order, treating each consecutive top-bottom duo as a pair (assume all days have even numbers of symbols, ensuring complete pairing; list all pairs in order). Analyze the sequence of pairs across the days for patterns, such as repetitions, cycles, transitions between pairs (considering the rules for FBS), day-of-week correlations, numerical day influences, skips and day gaps, or other logical progressions. Prioritize transitions (most common follow-ups to the previous day's pairs), low repeat rate (repeats ₂₀-25% of transitions; reduce likelihood of predicting recent pairs), FSB frequency (prioritize FSB-involving pairs over FBS), and overall frequency (common pairs appearing 4+ times). Ensure the analysis is based solely on the transcribed symbols from this specific calendar, without assuming or carrying over patterns from any other calendars. Based on this analysis, predict the most likely paired symbol(s) that would appear on the prediction day (e.g., August 21), providing only the top prediction in the format "X + Y" (where X is top, Y is bottom). If no clear pattern emerges with >70% confidence, state "No high-confidence prediction possible" instead. Include a confidence percentage (e.g., 95%) based on how well the pattern matches. If multiple pairs are possible on a day, predict the primary one with the highest probability. Do not guess randomly; ensure the prediction is logically derived with high confidence (>70%), and adjust confidence downward if the pattern is weak or inconsistent. Do not include the steps how you determined the prediction. Only display the prediction.
