I wouldn't think there's really any legitimate doubt, that game officials, in general are NOT trying to favor either team as to how they manage the game clock, initiating or stopping play Perhaps I'm just blessed not to have encountered, or been exposed to a lot of "other officials" who inject their personal preferences and biases into pressure situations to benefit, or hinder, particular teams.
Not to sound overly pessimistic, but I'm afraid High School Football is a somewhat different activity than Collegiate or Professional football, simply because it's played by younger (High School age adolescent and younger) athletes than those having reached "advanced", higher levels. (In essence, no matter how much technology you wrap HS football in, it will still be played by HS students)
Continued effort to achieve consistency in many phases of officiating is an ongoing, and constant, valuable pursuit. However, as reality strongly suggests; no two football PLAYS, much less entire games, have EVER been EXACTLY alike, and management of the game (being observed) should be based on complying with existing standards, that are consistently applied based on what is actually being observed.
We should all understand that football participation is a performance pyramid that tests and excludes participants at each level, based on knowledge learned, skills developed and abilities and potential identified. What may work at one level, may not prove appropriate at other levels.
Currently, a practical standard is recommended of; declaring a ball RFP within 12-15 seconds of it becoming previously dead, UNLESS OF COURSE some valid reason for delaying the RFP surfaces and requires dealing with. This sounds like a reasonable, practical and appropriate objective worthy of our attention and compliance WHENEVER POSSIBLE.
Situations than interrupt being able to comply with that (or other reasonable) standard exceptions, are most often, unique to the game they occur within and the existing standard allows the flexibility to deal with unique situations, individually and appropriately.
Managing sidelines, that allow emotions to sometimes cloud their behaviors, is an extremely valuable ACQUIRED SKILL, that although time consuming, is well worth the effort and patience of acquiring. Additional concentration on mastering those skills, may prove a more effective method of dealing with a greater variety of frustrations than try to deal with each frustration individually, with an additional technology.
We often discover that persistent problems are caused less by perceived ineffective performance than simply unreasonable expectations, and focus on performance alone may not ever provide satisfaction.
