Grade Record Interpretation

To interpret a grade record for In-Person Instruction (IPI) (but NOT Remote Instruction (RMI)), consider the example complete grade record with explanatory notes in brackets NOT found with an actual compact grade records:

10  flamester        Cumulative Ave.= 76.70  Dev.=  0.264  Letter Grade=B        (Alias,Cum.average,letter grade)
Ave= 91.3     1    1    1    1    1    1    0    1    1    1    1    1    1    1 (RHSTs)
              1    1    1    1    1    1    1    1    0                            
Ave=100.0    -1   -1   -1   -1   -1   -1   -1    1    1    1    1    1    1    1 (Group activities)
              1 -202
Ave= 76.7                                                                        (Cum.average repeated)
Ave= 72.9    42   63                                                             (Exam average and raw scores)
Ave= 71.0    71                                                                  (Final exam average and raw score) 

1. Items with no entries are assigned the cumulative average---for no good reason.
2. Some reading and group activity marks for students will be incomplete:
   1. Sometimes I miss group activity slip, but sometimes forget to hand them in or put their names on them legibly.
   2. Sometimes students have NOT noticed that the Course Site / Preliminary Schedule is RHST -1 and has to be reported to get the first RHST mark.
3. Students should bring any corrections needed to my attention ASAP.
4. Note 4: A stab at describing how group activity drops are done: My grading computer program always drops the 7 lowest activities after 8 non-special-dropped activities have accumulated and the lowest dropped ones are marked by a minus sign, except dropped 0's are turned into -201's since -0 is the same to integer arithmetic as 0, but since activities are only 0 or 1, the lowest ones that arn't turned into -201's are turned into -1's which disappear once seven or more real zeros have accumulated of which the first 7 zeros are turned into -201's and the others stay 0's, and the dropped activities (non-special and special) are dropped from the numerator and the denominator that calculates the average, and furthermore special drops are -202's which don't count toward the 7 drops, but I allow at most 5 special drops and if more are needed and the activity hurts the student's grade, then I just drop the whole activity item so that it doesn't count either way and this is done by turning all grades into -202's which is klutzy, I know, but there is still an average on the activity line, but it isn't for activity, it's just the cumulative average shown as a placeholder.
5. A formula way at describing how group activity drops are done:

                 T = number of activity points:  i.e., count of 1's
                 A = number of activities:  All that actually occurred in class.
                 d = number of drops which is always 7
                 s = number of special drops which always < = 5
   
                 Activity Average = ( T - d - s )/(A - d - s) for A - s > = 8
                                  = ( T - s )/(A - s)         for A - s < = 7
                                  = not counted               for A - d - s = 0
                                                              but the activity line
                                                              shows the cumulative average
                                                              as a placeholder.
                                  = 0 but counted             the activity line
                                                              shows the cumulative average
                                                              as a placeholder which is 
                                                              klutzy, but for some historical
                                                              that's what happens.
