Making adults & teens & pre-teens utter formulaic "decisions for Christ" phraseology is easily reduced to a 'cheap and ineffective way to assuage' the church's responsibility to disciple people in-depth as they try to make the target Heaven-bound minus a Lordship relationship with Christ and full assimilation into His Body, the Church.
Baptism comes after the intellect-capable commitment to Christ, not before. Anything else is ascriptural.
