Alright fine.
So
25 mins before departure you request a buggy
15 mins you decide to abandon the buggy and walk
Even if your gate is 1-30 (which is roughly your 5 minute walking time from wing) you would've been below the time you're in the absolute right (see iamhappy's quotation of e-ticket 20 minutes

10 minutes is practice. 20 minutes is what's stated on Eticket (also what they've stated on CX and KA gate map attachments til relatively recently) - that's why I asked you to define gate close - cos your gate close is what I too use as an absolute minimum but it's not policy.
