Scope & estimate
Everything in one breakdown: the 2027 Improvements features grouped by the planning doc's priority tiers, followed by the committed engineering streams. Hours and descriptions are grounded in a review of the codebase — where existing infrastructure or data already covers part of a request, the estimate reflects it. Feature rows are tagged by version — WebMobileBoth — and clarifications from the doc's review comments are folded into the descriptions and marked in blue. The doc's "School Mode / graduating year" request is delivered by Stream C (Age grids) below. Every group is independent and can be scheduled or billed on its own.

Customizable scoringThe rating widget already accepts a min/max range — so the work is storing a configurable range in settings and threading it through where scores are entered. Per review: allow different ranges per skill (jumps 1–5, tumbling 1–10), which also means normalizing an athlete's total across mixed ranges.

Email tryout videos to parentsReuses the existing AWS SES email pipeline, but athletes have no parent-contact field today — so this adds parent-email capture (athlete form + roster import) plus a new send view. The most-requested item. Per review: needs a new workflow; design to be prototyped first.

Split stunt position "Base" into Main / Side BasePer review: split "Base" into two positions (not a rename), so Coach Determination reads Flyer, Main Base, Side Base, Backspot, Tumbler. Touches the web Position enum, the mobile position list, position filters and the stunt icon, plus a migration of existing "Base" values.

Timeline & confidence
The full estimate is roughly 108 hours of development. Nothing here is all-or-nothing: every priority tier and each committed stream is independent and can be scheduled in any order, so work can start with the Essential items and the committed streams and proceed down the list.
How firm these numbers are. Hours are grounded in a codebase review, so the descriptions reflect what already exists (the rating widget's range support, the SES email pipeline, the existing flag field, Expo 57's byte-range reads). The softest figures are the design-dependent items — customizable scoring, email to parents, and the multiple-locations rework — which each warrant a short design pass before their build and could move once scoped. Estimates exclude any AI-assisted acceleration and assume "how-to" video content is produced separately.
